Pigeon baby bottles: Two large and two small glass bottles Two large and two small plastic bottles. There are 4 caps And 3 connecting parts. They have been washed, but please wash them again before use. ⭐︎Nipples are not included, so please purchase them separately. The glass bottles are easy to cool, so they were convenient for use at home. The plastic bottles are light, so they were convenient for going out. I recommend having both, as you can use them according to your needs.
