Review: Great inserts for Elvie Stride - made pumping comfortable and more productive - I was initially putting off getting inserts as I wasn’t sure they were worth the extra cost and didn’t think they would make much difference. I was wrong. These are great! 2 sets (4 flanges) for just a bit over a fiver. They are very substantial (surprisingly so given they are 21mm for a 24mm shield, so don’t have much space to play with) and comfortable. They slot into my pump (Elvie Stride) very easily and sit flush. They even have a little tab to help pull the flange back off the shield for cleaning. I had previously bought a multipack, but if you know your size these are a much better buy - in a multipack you’ll only end up using one set of four or five as the others won’t fit. This way I get 4 usable flanges for half the price of any other sets, and they are much better quality. They have made pumping more comfortable and significantly increased my yield. Review: Good quality - Helped with supply ## Features - 【Perfect Fit for Your Nipples】KISSBOBO Flange Inserts to help you find the right fit for your nipples. They're compatible with Medela PersonalFit 24mm Shields, Spectra 24mm flanges, Willow 24mm flanges, and Momcozy S9/S10/S12 Wearable Breastpump 24mm cups. They'll reduce the 24-mm shield nipple tunnel down to the correct size (not for 27mm shield). - 【Compatible with Most Wearable Breast Pumps】 These inserts work with any S9/S10/S12 Wearable Breast Pump, including popular brands like Momcozy, TSRETE, Luxlady, and more. They're also applicable to most other brands of models for 24-25mm (Freemie) and compatible with MISSAA hands-free breastpump. - 【Comfortable and Efficient Pumping】 The size of your flange insert is important for comfort and efficient pumping. Some moms experience nipple swelling while milking, so it's important to observe the appearance of the nipple during pumping. - 【Safe and Easy to Clean】 Our flange inserts are made of food-grade silicone and are BPA-free. They're easy to clean and maintain, so you can use them with confidence. - 【Warm Tips】 The usage time of accessories depends on the practical frequency and cleaning method. We recommend that the accessories of the breast pump be updated every three months. However, if any damage or mold is found, the accessories should be replaced in a timely manner for hygiene and normal use needs. If you are unable to determine the issue with the accessories, please contact the KISSBOBO after-sales team in time. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CC1J6SDY | | Best Sellers Rank | 31,703 in Baby Products ( See Top 100 in Baby Products ) 642 in Breast Pumps & Accessories | | Brand | KISSBOBO | | Brand Name | KISSBOBO | | Colour | Off-white, 4pcs | | Customer Reviews | 3.1 out of 5 stars 3 Reviews | | Dishwasher safe? | Yes | | Is the item dishwasher safe? | Yes | | Manufacturer | KISSBOBO | | Manufacturer Part Number | Flange-21mm-4pcs | | Material | Silicone | | Material Type | Silicone | | Power Source | Battery Powered | | Power source | Battery Powered | | Special Features | Hands Free Usage, Portable, Wear | | Special feature | Hands Free Usage, Portable, Wear | | Unit Count | 1.0 count | ## Product Details - **Brand:** KISSBOBO - **Special feature:** Hands Free Usage, Portable, Wear - **Material:** Silicone - **Power source:** Battery Powered - **Number of items:** 4 - **Dishwasher safe?:** Yes - **Size:** 21MM 4PCS - **Manufacturer:** KISSBOBO ## Images ![KISSBOBO Flange Insert 21mm, Compatible with Lansinoh /momcozyS9/S10/S12/Medela/Willow/Elvie/TSRETE/,Portable Breast Pump Shields/Flanges,Milk Collector 24mm Universal (21MM（4PCS）) - Image 1](https://m.media-amazon.com/images/I/61Gz4Zt9LeL.jpg) ![KISSBOBO Flange Insert 21mm, Compatible with Lansinoh /momcozyS9/S10/S12/Medela/Willow/Elvie/TSRETE/,Portable Breast Pump Shields/Flanges,Milk Collector 24mm Universal (21MM（4PCS）) - Image 2](https://m.media-amazon.com/images/I/61HO-LM2ZrL.jpg) ![KISSBOBO Flange Insert 21mm, Compatible with Lansinoh /momcozyS9/S10/S12/Medela/Willow/Elvie/TSRETE/,Portable Breast Pump Shields/Flanges,Milk Collector 24mm Universal (21MM（4PCS）) - Image 3](https://m.media-amazon.com/images/I/71qiJAE2bQL.jpg) ![KISSBOBO Flange Insert 21mm, Compatible with Lansinoh /momcozyS9/S10/S12/Medela/Willow/Elvie/TSRETE/,Portable Breast Pump Shields/Flanges,Milk Collector 24mm Universal (21MM（4PCS）) - Image 4](https://m.media-amazon.com/images/I/71lJXduEzqL.jpg) ![KISSBOBO Flange Insert 21mm, Compatible with Lansinoh /momcozyS9/S10/S12/Medela/Willow/Elvie/TSRETE/,Portable Breast Pump Shields/Flanges,Milk Collector 24mm Universal (21MM（4PCS）) - Image 5](https://m.media-amazon.com/images/I/61fWe3JzIhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great inserts for Elvie Stride - made pumping comfortable and more productive *by P***S on 26 October 2025* I was initially putting off getting inserts as I wasn’t sure they were worth the extra cost and didn’t think they would make much difference.
