This is a set of 5 Pigeon baby bottle nipples, size SS. Purchased in November 2024 and stored at home after my baby outgrew them. They were used for 2 months, so there is some wear and tear, but they are still usable. Please understand that these are used items. Please note that I will fold them for shipping as shown in the third photo. (They will not crease and will return to their original shape.) They have been washed and boiled, but please sterilize them yourself before use.
