## Features

- Struggling to get the right fit with your breast pump? LUXEMUM flange inserts for breast pump help you find the perfect size for your nipples.
- Our inserts (available in 13, 15,17, 19, and 21mm) reduce the 24mm shield tunnel down to the right size for you. That means a more comfortable and effective expression, adapting to your body’s changes during different stages. (Please note: These aren’t suitable for 27mm shield covers.)
- They’re designed to fit most breast pump — including popular ones like Momcozy, Nuliie, KISSBOBO, Lansinoh, Elvie, Willow Go, Spectra, and Medela
- Made from food-grade silicone and completely BPA-free, LUXEMUM breast pumps & accessories are safe and easy to keep clean. Just wash with warm soapy water after each use. You can also sterilise them using steam, boiling water, or a microwave steam bag — just make sure the temperature doesn’t go above 200°C
- Getting the flange size right makes all the difference. A good fit helps with comfort and efficiency. Some mums find their nipples swell a bit during pumping, so it’s helpful to keep an eye on how they look and feel. If you notice rubbing or your nipple pressing against the sides while pumping, it’s likely the flange isn’t quite the right size — and switching to a better fit should help
- How long your pump accessories last depends on how often you use them and how you clean them. We generally recommend replacing them every 1 to 2 months to keep everything working smoothly. If you spot any signs of damage, it’s best to replace them straight away
- Not sure if it’s time for a change? Feel free to get in touch with our customer support team — we’re happy to help.

### ⭐⭐⭐⭐⭐ An excellent measuring tool

### ⭐⭐⭐⭐⭐ Does the job
*by S***. on 6 December 2023*

I have previously exclusively breast fed through pumping and struggled with a supply issue for the entire 6 months. Both lactation consultants and feeding specialists through NHS services told me a 24mm flange was the correct size (my 1st and 2nd were 7&5 yes ago). Ordered one of these only to find that I should be using a 17mm flange which explains many of the issues I had previously had. What a useful item. I wish these were around during my previous pumping journey. I paid £3.99 which I feel is value for money.
