This is a Combi Nursing Textbook Lico nipple, specifically for the Lico bottle. It is a new, unopened item. I gave up on bottle feeding because my baby strongly refused NUK nipples. Therefore, I purchased this but never used it, and it has been stored in a cabinet. This is an M-size nipple for bottles, designed to support a return to breastfeeding. - Brand: Combi - Size: M - Target Age: 2-3 months to 18 months - Quantity: 1 piece For shipping, I will remove the nipple from the box and compress it for shipping via Yu-Packet Post Mini. The box will be flattened and included. If you prefer to have it shipped as is, I can accommodate this with an additional shipping fee. Please let me know in the comments. Thank you for looking. I am also selling used (about 2 times) NUK nipples.
