Set of 7 standard silicone nipples for baby bottles. Includes 5 SS size and 2 S size, for a total of 7. Only 2 of the SS size were purchased six months ago and are barely used. The others were used every other day for 1-2 months with my first child in 2023, and I saved them for my second child, but they weren't used. They are silicone, so they appear slightly yellowed, but I think they are still usable. I washed them with detergent and sterilized them with steam each time, but since they are for babies, please consider the above before purchasing. The plate they are on is not included, of course. - Quantity: 7 - Material: Silicone - Design: Standard baby bottle nipples Thank you for looking.
