Pigeon Breast Milk Freezer Pack 4-piece set. [Set Contents] ・80ml (20 sheets) x 1 box, retail price 1,210 yen ・160ml (20 sheets) x 2 boxes, retail price 1,320 yen x 2 ・Freezer Pack Adapter x 1, retail price 550 yen All items are new, unused, and unopened. Purchased in September of this year. I expressed breast milk for my first child, so I bought these in preparation for my second child, but I didn't end up needing to express this time. The adapter allows you to express milk directly into the packs. I'm including it with the freezer packs because it's difficult to sell the adapter on its own. Please only purchase if you understand that these have been stored at home. There are no pets or smokers in the house. I'm new to Mercari, but I will strive for polite and prompt service. Please feel free to ask any questions you may have.
