It's convenient to have a few of these and rotate them during the newborn period. I haven't used the caps much, so I don't think there are any noticeable scratches. I also have items that can be sterilized in the microwave, so I will offer a discount if you purchase them together. Purchase date: Around February 2020 Purchase price: About 3,000 yen Usage frequency: About 2 months Material: Heat-resistant glass *I am not considering selling these individually. *There may be water marks left from drying after removing them from the sterilizing solution. *Please use nipples compatible with slim bottles. #BabyBottle #Breastfeeding #Newborn #Pigeon #HeatResistantGlass #120ml #Slim #Bundle
