That was the quickest way to get them placed in. **Q: Will these inserts ever come in a 17 or 19mm like the other pump parts you provide? A 21 is still too large** A: Freemie offers an OEM insert for their collection cups down as small as 15 mm, although price is considerably more than Maymom. **Q: how often should cushions be replaced?** A: I personally didn’t replace them unless they tore because I washed them after every use **Q: Does this fit the elvie stride?** A: Yes it does. It's a tight fit but you can make it work. ## Frequently Bought Together - Maymom Flange Inserts 21mm (Long) Compatible with Medela 24mm PersonalFit Shield, Spectra 24mm, Freemie 25mm Cup, Willow 24 mm Cup, Compatible with Momcozy Wearable 24mm Cup (S9, S10, S12); 2pc/pk - Maymom Flange Inserts 19 mm for Medela, Spectra 24 mm Shields/Flanges, Momcozy/Willow Wearable Cup.
