Willow Sizing Insert Set (2-pack)

The smaller flange opening finally seals properly around me, so I’m not wrestling with leaks mid-pump. These inserts click in snugly and the two-pack means I always have a clean one ready. Makes a huge difference for anyone with a petite fit.

Two pumps in and I already notice the difference—the insert holds the flange snugly without any gaps, and the 2-pack means I always have a clean backup ready. Wish I'd grabbed these weeks ago, honestly.

Finally, a proper fit for my smaller flange size—these inserts lock in snugly and make pumping feel way less awkward. The 2-pack means I always have a clean one ready when I need it. Wish I’d bought these sooner.
