Nursi Luna Flange Inserts 10PCS 13/15/17/19/21mm for 24mm Flanges/Shield of Most Pumps, Flange Sizing Kit Silicone Flanges Insert, Breastfeeding Essentials Kit for New Moms

I have the lansinoh duo discreet with these silicone flange inserts. I get the same amount when pumping with these as I do with my regular pump and have found them very easy to use.
