Up for sale are NUK bottle nipples and sippy spouts. These have been checked for extra holes, cuts, etc. They are in good used condition. There are 10 nipples with the y cut slit and 10 sippy cup spouts. I tried to get a picture of the nipple top so hopefully you can compare it to yours. These aren’t marked with an s, m, or l so I’m not sure what flow. Any questions please ask. I will send an extra of each nipple in case I have over looked something. Thank you for looking and please be sure to check my other auctions for combined shipping costs.
