## 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 breast 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 breast 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 breast 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.
- The lifespan of LUXEMUM accessories depends on usage frequency and cleaning methods. We recommend replacing your pump accessories every 1 to 2 months to ensure optimal performance. However, if you notice any damage, it's important to replace them promptly for normal usage. If you are unsure about the condition of your accessories, please contact our customer support team without delay.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great set to gauge correct sizing
*by K***L on 8 November 2024*

I've been using my pumps for maybe a month, and really struggling at times to get decent suction. I'd been wondering why and trying to figure it out. I had initially sized my nipples with a generic sizer, the card with holes cut out, and thought I was using the correct flange size. I got sick of struggling to get suction, so decided to see if it was a size issue, so I gave these a try. Long story short, great product so far, easy to use, good quality and work great with my Momcozy S12. They have definitely improved suction and as such I hope will improve output.

### ⭐⭐⭐⭐⭐ Exactly what you need for breast pumps
*by K***R on 18 April 2025*

Great product! Plenty of different sizes, comfortable and easy to clean!

### ⭐⭐⭐⭐⭐ Really nice
*by A***L on 31 July 2025*

As described, I love these inserts I use these in my Momcozys ( s12 and M9) and I use in my eufy as well. Good value for money
