This is a maternity preparation set from Pigeon's popular "Breastfeeding Realization" series. Since I was exclusively breastfeeding, I didn't have the opportunity to use the feeding bottle-related items, and they have been stored at home. I would be happy to pass them on to someone who is about to welcome a baby. Set Contents: 1. Breastfeeding Realization Feeding Bottle (plastic) 160ml * Color: Green * Condition: The outer film has been removed, but it is unused. 2. Dedicated Replacement Nipple SS size (1 piece) * Target: Newborns ~ (around 0 months) * Condition: New, unopened 3.

Product Condition: * All items are unused. * The feeding bottle body was stored with the film removed, so I will wipe the outside with a disinfectant sheet before packing, just in case. * There are no smokers or pets.
