Inquiry (采购产品): Avent ISIS Breast Pump Part Hello, I am looking for a replacement part of the manual Avent pump. It is the white circular part that allows the suction for the pump. It is about as big as a nickle and has an astrick design on one side while a smooth surface on the other side. Please let me know if you have that part, the price and how I can obtain it (through mail or physically). Thank you for your time, Trimee **** Hidden Message ***** Trimee Santos 92126 Company: Home Sweet Home San Diego E-mail: homesweethome_05@hotmail.com **** Hidden Message ***** homesweethome_05@hotmail.com
