I purchased these two years ago when preparing for childbirth. I accidentally bought too many, and they didn't match the number of bottles I had. I'm selling the unused ones that I found while organizing. Nipples are surprisingly expensive, so I hope to pass them on to someone who needs them. The nipples have been stored without being taken out of their nylon packaging, but please sterilize them before use on a baby. The box will be folded for shipping. The nipples will only be protected from water damage, so please be aware of this.
