160ml multi-fit baby bottle made of heat-resistant glass. This item is being sold without a nipple. The buyer will need to purchase a nipple separately. Please purchase a wide-mouth type nipple. I bought this when my son was refusing to use baby bottles, and I was trying out various bottles and nipples. However, he didn't seem to like this one either, and I only used it once or twice. The box has been opened because I took it out. I threw away the instructions, so the bottle is being sold as is. Second photo: Chuchu slim type baby bottle, plastic. This one has also been opened, but I've only used it two or three times. All instructions are included. The nipple is attached and has been sterilized and cleaned, but if you are concerned, please discard it and purchase a new one. I will wash and sterilize everything before shipping! You can buy both bottles as a set, or you can buy just one. If you only want one, please leave a comment first. If you are buying both as a set, you don't need to comment. For those looking for various baby bottles because their baby refuses to use them, for those who are about to have a baby, for those who want to save money, etc., please consider purchasing these!
