This is a transparent glass baby bottle. Thank you for looking. Pigeon's glass baby bottle, 160ml Includes one S-size nipple Only items shown in the photos are included. I was exclusively breastfeeding, so I only used this during the newborn period. The S-size nipple was used during the newborn period. Two stick packs of formula are also included. Please refer to the photos for the expiration date. There are no noticeable stains, but please refrain from purchasing if you are concerned as this is a used item. Thank you.
