This is a set sale including: ◉ Pigeon Manual Breast Pump ◉ One 160ml bottle included with the breast pump ◉ Breast milk freezer pack adapter ◉ Combi bottles: two 260ml bottles, one 160ml bottle ◉ Combi bottle sterilizing case (microwave use) - "Jokinjozu" All four bottles are made of plastic. The breast pump has its box and instruction manual. It has been stored at home after sterilization. For hygiene reasons, the nipples will be removed before shipping, but please comment if you would like them included. ※ Please wash and sterilize before use. Since I was exclusively breastfeeding, the Combi bottles were used about once a month. The 160ml bottle included with the breast pump (photo 9) was only used once for the bottle part. Also, the breast pump was used for errands where I couldn't take my child, so it was used only a few times. The bottles, sterilizing case, and breast pump are all stored at home and have minor scratches and scuffs from normal use. Please understand that these are used items before purchasing. Thank you for looking.
