Ardo Silicone chest bell insert 17 mm (Hands-Free, 2 pcs.)

A pair of breast shield inserts with a diameter of 17 mm made from soft silicone. This breast shield insert reduces our Hands-Free breast shield from 24 mm to 17 mm in diameter. (They cannot be used with other pump sets, only with the Ardo Hands-Free pump set with a 24 mm breast shield!) The correct breast shield size is important for efficient and pain-free pumping. You are using the right size if your nipple can move freely within the funnel, only a little or no part of your areola is drawn into the funnel, and the milk flows well during pumping.
