Review: Fits perfectly - The flanges fit perfectly into my lansinoh duo. I'm extremely greatful to finally have some flanges that fit and they were much cheaper than if I bought them from lansinoh. I also liked hoe i could try multiple different sizes. I appreciate the sizing chart too. I found out the nurse at my hospital had measured me wrong and that is why all the flanges I kept trying were too big.
Review: Fantastic product!!!! - The pump I got through my insurance has only 24mm flanges and the extras were expensive and I honestly didn't even know what size I needed. I just knew they didn't fit and they really hurt me. I was barely getting one to one and half ounces each pump too. I took a chance on these, I got the sizing tool too. One of my girls is a 20mm the other is a 19. There's a considerable size difference with them but I try to remember they're sisters, not twins. I put the 21mm flange insert in my existing flanges and the very first pump I did, I produced 3.5 ounces. First time ever in my entire pumping experience with two babies have I ever got this much. There was no pain during pumping either. The only con I can say about them is when you take them off after you're done, the suction is a little pinchy right where the edge of the insert is. They're super flexible though and do provide a little bit of cushion against the hard plastic flange. I'd buy these again, I'm so happy with my purchase. They're real affordable and for the price I didn't know what to expect. I was just desperate to try anything. Buy them!!!

## Features

- LUXEMUM shield covers and flange inserts help you find the perfect fit for your nipples. Flange inserts 13/15/17/19/21mm (10pcs) can reduce the 24mm shield nipple tunnel to the correct size (13mm/15mm/17mm/19mm/21mm), adapting to changes during different physiological stages for better breast expression. (Please note: Not suitable for 27mm shield covers).
- LUXEMUM inserts are compatible with most of wearable pumps, including popular brands like Momcozy, KISSBOBO, Lansinoh, Elvie, Willow go, Spectra, and Medela Freestyle Flex. They also work with most other brands' 24-25mm models and are compatible with the MISSAA hands-free pump.
- LUXEMUM accessory inserts are made of food-grade silicone and are free from Bisphenol A (BPA). They are easy to clean and maintain – simply wash with warm soapy water after each use. You can also use steam, boiling water, or a microwave steam bag for sterilization (temperature must not exceed 200 degrees Celsius).
- The size of the LUXEMUM flange insert is crucial for comfortable and efficient pumping. Some mothers may experience nipple swelling during expression, so observing the appearance of the nipples is essential. If you feel friction or compression on your nipples in the flange groove during pumping, it indicates an improper flange size, and you should switch to the correct-sized flange.
