selling two momcozy breast pumps. I used them twice and wasn't able to pump. They are pretty much brand new! Quiet design and no pain, no tube, no wire, moms can be worn inside a standard nursing bra, so you can pump completely hands-free. It's more portable and easier for you to carry when you are working. Safe material, soft food-grade silicone, suitable for a variety of chest types, and not strange smell. Anti-backflow design, avoid backflow or overflow of milk. Two modes, five leves, massage first and then pump, imitating the baby's feeding mode to optimize milk production.
