I am selling this item because I no longer need it after weaning. It can also be attached to the popular Nishimatsuya baby bottles. ⚠️ Please note that the set does not include the baby bottle, nipple, or lid. ⚠️ Breast milk bags (42 pieces) (+1000 yen) [sold separately for 1100 yen], and a breast milk bag adapter (+300 yen) [photo 4] are also available. Please comment if you would like to purchase them.
