Pigeon Hospital and Maternity Clinic Feeding Bottle (Direct Attachment Type) 100ml The KR-100 is a feeding bottle often used in hospitals and maternity clinics, compatible with the Mother's Touch direct-attachment nipple. [Contents] Pigeon Feeding Bottle (100ml) Heat-resistant glass x 4 bottles Feeding bottle cap x 2 [Set of 4] ▶ 2 bottles and caps Used during the newborn period. Used for one month. Disinfected after each use. ▶ Remaining 2 bottles Washed and stored after purchase. I bought 4 bottles for spares, but I washed them each time and used only 2, so these 2 bottles are unused. This is a set sale. How about it for feeding during the newborn period?
