Thank you for viewing. This is a set of two 200ml Betta baby bottles. These "glass baby bottles" are handmade by glass artisans who understand the properties of glass. They are resistant to odors and can be kept clean. Also, because they conduct heat well, it's quick to cool down after pouring in hot water, saving you time. I will wash them again before shipping. For hygiene reasons, nipples are not included, so please purchase them separately. I also have other baby items for sale, and if you purchase them together, I can offer a further discount, so please feel free to ask in the comments!
