Why it lives in the nook
Before the colours and the bundles there was this: ten clear silicone inserts, a ruler and a brush in a simple box. Thousands of mothers have measured with it, and it is still the plainest way to stop pumping in a shield that is too big.
- One pair of every size 13, 15, 17, 19 and 21mm, so you can test the next size up without ordering again.
- Nipple ruler included Read your diameter in seconds and choose the insert that matches.
- Soft on sensitive skin Cushioned BPA-free silicone that still lets milk flow freely.
- Boil or wash Sanitise in boiling water or clean with the sponge brush in the box.

Good Quality and Fit All My Pumps!
“I love this kit!! My flange size has changed a couple times throughout my breastfeeding journey and this kit has all the sizes I have needed. The flanges are great quality and have fit in my spectra, baby buddah 2.0, and momcozy s12. Would highly recommend!”
