☆ New, retail price 1870 yen. Made of durable silicone rubber. ● LL (Y-cut) for 9+ months (Drinking guideline: approx. 5 minutes for 200ml) Set of 5 (1 unused, new) Since I have twins, I used these frequently, and they are yellowed. I sterilized them with Milton and stored them wrapped in plastic wrap. Please wash them yourself when they arrive. I initially hesitated to list these, as I understand that some people may be concerned about hygiene with used items that go in the mouth. However, hospitals reuse nipples and bottles after sterilization, and it seems that nipples that have become softer from use are sometimes easier for babies to drink from. I was also told by nurses that "the more yellowed ones are often easier to drink from." Since it can be expensive to buy all baby supplies new, I would appreciate it if anyone who understands the situation would consider purchasing these. Please note that if there are no buyers, I will dispose of them, so please refrain from criticisms or opinions regarding hygiene. . .
