## Overview

Made from BPA- and DEHP-free materials, these inserts ensure a safer, more comfortable pumping experience with a secure fit and easy maintenance.

## Description

After market silicone insert compatible with Freemie 25 mm cup. Reduce the nipple tunnel down to 17 mm.

Review: Great multipurpose use for those with smaller nipples - I was able to use this flange insert not only with my Freemie cups, but also with my Willow 2.0 24mm Flange. Freemie System The fit with the Freemie cups is incredibly sturdy. It was difficult to get out at first, but after I knew to twist instead of pull, dismantling and washing was a breeze. Willow Pump These fit into the 24mm flange loosely. I don't think it affected the suction despite the looseness. I just had to get used to holding in the flange insert when I went to take out the milk bag from the unit, so the flange insert wouldn't fall to the floor. Otherwise this made pumping with my willow significantly more comfortable and increased when using the Willow.
Review: Works great for Freemie closed collection cups - I used these flange inserts for my Freemie closed collection cup system. They fit in REALLY nice and tight. In order to clean them out well, you have to remove them each time which is somewhat of a pain. However, this is to be expected for a tight fit. I found that using the nipple brush in the base of the Munchkin bottle brush (the one with the silicone nipple brush that stores in the handle) to pop them out before cleaning was WAY easier on my hands. I sanitized them each time with steam and they held up well. I would recommend these.

## Questions & Answers

**Q: Will these work with medela / spectra 24mm flanges? what about the 24mm elvie?**
A: Haven’t tried the 17 mm but the 19 mm definitely worked for the Elvie. The instructions read to insert into the 24 mm flange which resulted in no suction. Tried inserting into the 21 mm flange and the suction was great. Definitely worked much better.

**Q: Which works better, the flange with the 17mm inserts or the 17mm flanges? I’m wondering if the softer material might get better results?**
A: Freemie doesnt sell 17mm flanges. Their default is 25 mm.

Maymom sells 17mm flanges. I had both. Liked both. Same results. Choose whichever is more convenient for you. I ended up loving the Freemie cups with the Maymom inserts.

**Q: Is it compatible with Medela Swing?**
A: Yes

**Q: Can I insert in a 19mm cups or it’s only for 24mm cups?**
A: They will not fit in a 19mm. They’re made for 25mm, but will fit into a 24mm...however, when inserted into a 24mm flange they stick out a bit but it doesn’t affect suction.
