The inserts are soft, flexible, and easy to place inside the 24mm flanges, and they instantly improved the fit.

Review: No regrets buying this set. Big thanks. - Loving these. Very comfy. Works great. Fits my Specta S1 well.

Much more comfortable than using the machine's ill-fitting size 24 stock flange. Because of the range is sizes I was able to get a pair for me without the stress of potentially getting the wrong size and a set that fits my roommate who's also a new mom. ## Features - Compatibility: The Flange Inserts 8pcs are breast pump accessories that can be used with most 24mm Shields/Flanges.Compatible with any S12 pro/S9 pro/S12/S9/TSRETE/Medela/Spectra/Opnmina/Elvie/Willow/Bellaaby/Motif Luna/Ameda/MOMMED/MYA/Ainsir/Phanpy/Lulia/NaNaLazy/Luxlady/kidzio/eulumap/Teexin/Fisroa/KISSBOBO/Goldeep/BIOBOO/Mumeasy/Nanawawa/TOVVILD etc 24mm flange/shield(Not for 27mm flange/shield) - Usage: GOCROWEEN flange inserts sets contain two of each size (5 sizes in total), which can be used to find the correct size for your nipples.

I recommend getting a spray bottle of water and spraying inside the flange before trying to put these in so that they slide in and out a little easier. It’s also a lot easier to clean water than to use nipple cream. ## Frequently Bought Together - Flange Inserts 17mm 8PC Compatible with Momcozy S12 pro/S9 pro/S9/S10/S12/Medela/TSRETE/Spectra/Bellababy etc 24mm Wearable Breast Pump, Reduce 24mm Tunnel Down to Correct Size - Medela Manual breast pump with Flex Shields Harmony Single Hand for More Comfort and Expressing More Milk --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.dk/products/587800604-flange-inserts-17mm-8pc-compatible-with-momcozy-s12-pro-s9](https://www.desertcart.dk/products/587800604-flange-inserts-17mm-8pc-compatible-with-momcozy-s12-pro-s9) --- *Product available on Desertcart Denmark* *Store origin: DK* *Last updated: 2026-09-17*
