Please comment before purchasing. Danish-made glass baby bottles. The nipples are made of 100% natural rubber. Since only silicone is used in Japan, there are almost no other baby bottles with natural rubber nipples besides this one. Two 110ml bottles. The nipples must be sterilized with boiling water, but the bottles can be used in the microwave and dishwasher. Recommended for babies who refuse baby bottles. Please understand that these are used items. There is no box. Only the nipples and bottles themselves. (Can be used immediately after sterilization) My child also refused baby bottles, but we got them used to these and then transitioned to Japanese silicone bottles. (Now they love milk!) Since they are made of glass, I will pack them carefully, so the shipping cost is slightly higher. Thank you for your understanding.
