With a large 260ml capacity, it's convenient for use even as your baby grows. Compatible with Pigeon's Breastfeeding Realization bottles. This item is new and unused, as I didn't end up using it. Immediate purchase is possible. For shipping, I will remove the contents from the box to save on shipping costs. As a bonus, I will include samples of Mama & Kids' Pregnancy Care Cream, Be-up White, and Pigeon's additive-free Pure Baby Laundry Detergent.
