I purchased this new in 2025, but I haven't had many opportunities to use it, so I'm selling it. (It has only been used a few times.) The adapter has only had its box opened, but it is brand new and unused. The breast pump parts, instruction manual, and breast milk freezer bag adapter and baby bottles are not included. You can use it by attaching your own bottles from home. It will be shipped via Yu-Packet Plus.
