BPA-free food-grade silicone, wearable design breast pump S12 Pro. - Brand: momcozy - Model: S12 Pro - Material: BPA-free, food-grade silicone - Features: Wearable design - Accessories: Charging cable, instruction manual (Tested and working - please charge before use) Thank you for viewing. I accidentally purchased two of the same item, so I am selling the unused one. I personally use the same pump, and it's very comfortable and highly recommended because you can pump electrically just by putting it inside your bra.
