Choose your size, then your silver

1. Regular or XL: the real dimensions
XL has a 7 mm larger overall diameter than Regular.
| Size | Overall diameter |
|---|---|
| Regular | about 4.5 cm (1.8 in) |
| XL | about 5.2 cm (2.0 in) |

Prices and availability load from our store. Higher silver purity doesn't mean a better result for every mom or that a material suits every skin. If you have a known metal allergy, check with your healthcare provider first.

Questions before you choose
I'm between sizes. Which one?
XL is about 7 mm wider across than Regular. If you're unsure which size fits you, ask us before you order.
What if the size doesn't work for me?
Silver nursing cups are covered by our 90-day money-back guarantee. We don't offer direct exchanges at this time. Contact us first, and see our refund policy for how returns work.
Is Trilaminate solid silver?
No. Trilaminate cups are silver-plated: a copper core with an electroplated silver surface. 925 Sterling and 999 Pure are solid silver throughout.
925 or 999: what's the practical difference?
925 sterling is 92.5% silver alloyed with other metal, which makes it harder than fine silver. 999 is 99.9% silver and softer, so it needs gentler handling. Both are worn the same way.
Is tarnish the same as plating wear?
No. Tarnish is a normal darkening of the silver surface. On plated Trilaminate cups, wear can thin the silver layer over time, which is different from tarnish. Follow the care steps for your material in the care guide.
Can I use HSA or FSA funds?
Every order includes an itemized invoice you can submit to your plan for reimbursement. Coverage and approval depend on your plan, so check with your plan administrator.
