Purchased in January 2025 and used for about a month during the newborn period. There are no tears or rips, and it's still in usable condition. Please refrain from purchasing if you are sensitive to used items. I will sterilize it at home by boiling, and will sterilize it again before shipping. I purchased it for 902 yen (tax included) each. How about it for a spare or a trial? To ship it compactly, I may fold the nipple for shipping, so I will sell it to those who understand!
