## Description

desertcart.com : Maymom 21mm Flange Insert Pink Compatible with Elvie Single/Double Electric, Elvie Stride Cup (24mm), Compatible with Medela PersonalFit Flex Shield, Not Original Elvie Replacement Pump Parts : Baby

Review: So Comfortable! - I’m in my 3rd baby and I’ve tried a bunch of breast pump inserts, but these are hands-down the most comfortable I’ve ever worn. The material is so soft and smooth — none of that annoying sticking or friction I get with plastic or other silicone type inserts. I use them with Eufy wearable pump— no friction, no irritation, just pure comfort. Highly recommend if you’re over wrestling with discomfort. They offer smaller sizing which is extremely helpful if you need those sizes. Total game-changer!
Review: Worked good - Perfect fit and functioned the same as the originals

Perfect fit and functioned the same as the originals

### ⭐⭐⭐⭐⭐ Perfect
*by S***A on November 3, 2023*

These work great for my pump flanges that plug in the wall or my manual but they are to long for a mobile pump. Great quality and thick so they hold up well and they are very comfortable these are a life saver. (I’ve been pumping for a year)
