Pigeon Glass Baby Bottle, Mother's Milk Consultation Series, 1 bottle No outer box, instructions, or SS nipple. Purchased in 2022. Used every time for feeding for one month each in 2022 and 2025, but after that, used about once a day until around 3 months old to get used to the bottle. I think it's in relatively clean condition. After each use, it was hand-washed and sterilized in the microwave, and when it was last used, it was sterilized, dried thoroughly, and stored in a zip-lock bag.
