Purchased new in May of this year. Selling because it didn't suit my child. Used twice, then sterilized and stored. Pigeon → S size, 200ml NUK → M size, 250ml Both are plastic If you'd like to see any other areas, I can take additional photos, so feel free to comment! I think they are in relatively good condition, but please understand that they are used items, so please purchase only if you are okay with that.
