Pigeon Mother's Milk Real Bottle 240ml and 160ml, Set of 2 Purchased in 2021, used by two children for about a year each. Usage frequency was about 6 times a day for the older child, and 1-2 times for the younger child. There are scratches from use, but they still seem usable, so I'm selling them. Both are made of plastic. Nipples are not included.
