Pigeon Baby Bottles - Set of 2 Both are made of glass. 200ml x 2 bottles Glass bottles are resistant to scratches, stains, and odors, making them easy to clean and keep sanitary. I'm selling these because I no longer need them. They are used items, but there are no cracks and I think they are still usable. *Nipples are not included. Please understand that these are used items and have been stored at home before purchasing.
