Design and fit

The flange features a soft rim with a thicker edge, a smooth angle, and a long tunnel. This design aims to align well with the nipple and help establish a steady seal during pumping. The 17 mm option is part of a broader size range that includes 19 mm, 21 mm, 24 mm, and 26 mm to accommodate different preferences.

Materials and safety

Made from 100 percent food-grade silicone, these parts are BPA-free and skin-friendly for both mom and baby. Packaging is designed to be eco-conscious, and components arrive in a protective box for storage and gifting.

Care and maintenance

Cleaning is straightforward and quick. Rinse, steam, boil, or use microwave steam bags to sanitize. For best performance, consider replacing the flange every 2 to 3 months to maintain optimal function.
