If you have gone looking for silver nursing cups, you have probably noticed there are more brands than you expected, and every one of them claims to be the best. Silverette, MoogCo, Willow, Momcozy, Koala Babycare, Go Mommy, and our own RFC cups all sell some version of the same idea, a small dome of silver worn over the nipple between feeds. The differences are real, but they are smaller and more specific than the marketing usually lets on.
This is a full disclosure guide from a brand that sells one of these products. We make RFC Silver Nursing Cups, and we think ours are a strong option, but the most useful thing we can do here is explain what the actual differences between brands are, so you can judge that for yourself instead of taking our word for it.
What the silver purity numbers actually mean
Nearly every brand advertises a purity grade, and this is the single most confusing part of shopping for these. Here is what the numbers mean in plain terms:
- 925 sterling silver is 92.5% silver, alloyed with other metals (usually copper) for added strength. This is the most common grade in jewelry and in several nursing cup brands, including Silverette and MoogCo's tri-laminate construction.
- 950 silver is 95% silver, a step up in purity from sterling, used by brands like Willow.
- 999 fine silver is 99.9% silver, about as pure as commercially available silver gets. It is softer and more malleable than sterling, which is why brands using it, including Momcozy and RFC, tend to favor rounded, hand-finished shapes over sharp-edged designs.
- Tri-laminate (used by MoogCo and Koala Babycare) refers to a layered construction rather than a single purity grade, aiming to balance durability with a silver-rich surface.
There is no independent research proving one grade heals faster than another. Silver's natural antimicrobial properties have been used in wound care for a long time, and that reasoning is why the category exists at all, but the purity debate between brands is mostly about feel, malleability, and how the metal is worked, not a documented difference in outcomes.
How the well-known brands compare
- Silverette is the original in this category, handcrafted in Italy since the 1990s and the best-selling option in Europe. It uses 925 sterling silver. Its long track record and the fact that many lactation consultants already know the name are its biggest advantages.
- MoogCo uses a 925 tri-laminate construction and has built out detailed comparison content of its own, worth reading alongside this one.
- Willow uses 950 silver, sitting between sterling and fine purity.
- Momcozy uses 999 pure silver with a perforated design meant to improve airflow, and offers three size options.
- Koala Babycare uses a tri-laminate silver build and has one of the largest user review bases in the category.
- RFC (us) uses 999 pure silver, is nickel-free, and is hand-finished with rounded, folded edges specifically to avoid pressure points. It comes with a silicone fit ring, a cleaning cloth, a case, and a free breastfeeding e-book, and is sized in two options — one of the more complete kits in this comparison.

View on AmazonWhat actually matters when you are choosing
Once you look past the purity numbers, a handful of practical questions matter more day to day:
- Do you need multiple sizes? Breast and nipple size vary, and a cup that is too large can rub rather than protect. Brands offering more than one size (Momcozy, RFC) let you fit each side independently.
- What is included? A carrying case matters if you are pumping at work or traveling. A cleaning cloth and a fit ring (to help the cup sit securely under a bra) are small details that save you buying separate accessories. RFC also includes a free breastfeeding e-book with every order, written to answer the practical questions that come up in the first weeks, which none of the other brands here currently offer.
- Do the edges sit comfortably against your skin? Hand-finished, rounded edges make a real difference for comfort during long wear, regardless of purity grade.
- Do you want a cream-free routine? All silver cups are designed to be worn without lanolin or other creams. If you currently rely on a cream, switching to any of these brands is a routine change worth planning for.
Where RFC fits in
We built RFC around 999 pure silver specifically because it let us keep the metal nickel-free without needing an alloy, and around hand-folded, rounded edges because that is the detail our own testers noticed most during long wear. We are not the original in this category, Silverette has been around the longest, and we are not the only brand using fine silver, Momcozy also does. What sets our kit apart is what comes with it: two sizes, a silicone fit ring, a cleaning cloth, a case, and a free breastfeeding e-book written to answer the practical questions new mothers actually have in the first weeks. Of the brands compared here, RFC is the only one currently pairing 999 purity with that level of nickel-free, hand-finished construction and a genuinely useful included resource rather than just the cups themselves.

View on AmazonWhen silver nursing cups are not the right fit
In the interest of the same honesty this guide opened with: silver cups are not the right tool for every situation. If pain traces back to a latch problem, tongue-tie, or an active infection, a cup worn between feeds can make the gap between sessions more comfortable, but it will not fix the underlying cause, that still needs a lactation consultant or a doctor. Mothers with a known nickel allergy should double check purity and alloy content carefully, since not every brand on this list is nickel-free even at high silver purity. And if you already have a nipple care routine that is genuinely working well for you, lanolin, a hydrogel pad, simple air-drying, there is no requirement to switch, silver cups are one solid option among several, not the only correct answer.
Frequently asked questions
Is 999 silver better than 925 silver for nursing cups?
Neither grade is proven to heal faster than the other. 999 fine silver is softer and more malleable, which is why it is often hand-finished into rounded shapes. 925 sterling silver is harder and more scratch-resistant because of its added alloy. The choice mostly comes down to feel and how the cup is shaped, not a documented difference in results.
Do silver nursing cups actually work?
Many mothers report meaningful relief from wearing them between feeds, and silver's natural antimicrobial properties have a long history in wound care generally. They are not a substitute for fixing an underlying latch problem, which is the most common actual cause of nipple pain, so they work best alongside a good latch rather than instead of one.
How do I clean silver nursing cups?
Rinse with warm water daily and dry thoroughly, since trapped moisture is what causes tarnishing or staining, not the silver itself. A soft paste of baking soda and water can restore shine if a cup discolors over time. Avoid harsh chemical cleaners, which can be more abrasive than the silver needs.
Can I wear silver nursing cups while sleeping?
Most brands, including RFC, design these for wear between feeds, which for many mothers includes overnight. A well-fitted cup that sits securely under a soft, supportive bra should not shift much during sleep, but if a cup feels loose or is sliding, it is a sign that the fit or size needs adjusting.
Do I need a different size for each breast?
It is common for one breast to be slightly larger than the other, especially in the first weeks of breastfeeding. Brands that offer more than one size, including Momcozy and RFC, let you match each side independently rather than compromising with a single size for both.
How long do silver nursing cups last?
Silver does not wear out the way a disposable pad does, so most brands market these as a one-time purchase that lasts through breastfeeding and weaning, and often for a second child if stored properly in a case between uses.
What comes included with RFC Silver Nursing Cups?
Every RFC order includes the 999 pure silver cups in your chosen size, a silicone fit ring to help them sit securely under a bra, a cleaning cloth, a carrying case, and a free breastfeeding e-book covering practical first-weeks questions. It is one of the more complete kits among the brands compared in this guide.
Silverette vs. MoogCo: what's the real difference?
Both use 925 sterling silver, but the construction differs: Silverette is a solid sterling silver dome with decades of track record and wide recognition among lactation consultants, while MoogCo uses a tri-laminate build (a layered construction over a silver-rich surface) and leans on detailed side-by-side comparison content of its own. Neither has been shown to heal faster than the other, so the practical differences come down to brand history and price rather than performance.
How does RFC compare to Go Mommy silver nursing cups?
Go Mommy sells across several purity tiers (925 sterling, 999 fine, and 999 tri-laminate), all nickel-free, at a wide price range depending on the listing. RFC sticks to one tier, 999 fine silver, and pairs it with hand-folded rounded edges, two size options, and a kit that includes a fit ring, cleaning cloth, case, and a free breastfeeding e-book. If you want tier flexibility, Go Mommy offers more listings to choose from; if you want one consistent, fully-kitted option, that is where RFC is built to fit.
What's the difference between 925 and 950 silver nursing cups?
925 sterling silver is 92.5% silver (used by Silverette and MoogCo's base line), while 950 silver is 95% silver (used by Willow), a small step up in purity between sterling and 999 fine silver. In practice the gap between 925 and 950 is minor compared to the gap between either of them and 999 fine silver, which is soft enough to be hand-finished into rounded, seamless shapes rather than a stamped dome.
Is there a Silverette dupe worth buying?
"Dupe" is a loose way to describe the many similar-looking silver domes now on the market, since the basic shape is not patented. Budget brands like Boboduck and Nisxabebe undercut Silverette on price using 925 or tri-laminate silver, while RFC and Momcozy differentiate on 999 purity instead of just price. None of these are counterfeit Silverette products, they are independent brands competing in the same category, so the real question is which purity grade and included accessories matter to you, not which one is the "real" one.
Silverette vs. Momcozy vs. Willow: how do they compare?
Silverette uses 925 sterling silver and has the longest track record. Willow uses 950 silver, a step up in purity. Momcozy uses 999 fine silver in a perforated design meant to improve airflow, and is one of the few brands besides RFC to offer more than one size. All three are worn the same way, between feeds, without creams, so the choice mostly comes down to purity preference, sizing needs, and what is included in the box rather than a difference in how well they work.
Which silver nursing cup brand is actually best?
There is no single best brand, since none has been shown to heal faster than another, but there is usually a best fit for your situation. Silverette and Koala Babycare lead on sales volume and reviews if a long track record matters most to you. Momcozy and RFC are the two offering multiple sizes if fit is your priority. RFC is the one bundling a free breastfeeding e-book with every order if you want more than just the cups.
