Willow Innovations Inc - Flange Set Willow® 3.0 For Willow® 3.0 Breast Pump [2/PK] (1226117_PK)

Flanges are interfaces between the breast and the breast pump; a flange creates a seal around the breast, allowing suction to be applied to extract milk from the breast efficiently. Clear flanges have a quick-snap closure for easy placement and fast assembly. Use these flanges with Willow spillproof milk bags. There are a pair of 21 millimeter flanges in a pack.
