Willow Universal Pumping Sizing Insert, 21 mm

The Willow flange inserts were honestly one of my favorite parts of the pumping experience. They are incredibly comfortable and made a huge difference for me, especially having sensitive nipples. Compared to other flange inserts I've tried, these felt much softer and more natural while pumping and helped prevent the soreness I usually experience. They also created a much better fit, which made pumping more comfortable and efficient overall. I highly recommend the Willow flange inserts if you're struggling with comfort or flange sizing. They made pumping feel significantly gentler, and more comfortable.

These are very helpful especially since each nipple isn't necessarily the same size. I get a better pumping experience with them and it is very comfortable

I love these inserts!!!! I have tried multiple other brands and these are so soft and very easy to clean. Plus the cute flower pattern is a nice touch. I would buy these again.

I really recommend getting these inserts. You can select your size and get multiples. It comes with 24mm and then 21mm inserts, which most of us girlies are not that size. Worth the money!

These inserts are much more comfortable than the standard silicone inserts I've used before. The quality of them are great and they fit snugly in the flanges of the Willow.

I needed to start pumping early for my baby so she could bottle feed. These were much more comfortable than my regular pump so I preferred using the Willow with them over my main corded pump.

I'm a second time mama and I always wanted a Willow. I decided to get the Willow Go and the inserts. They fit perfectly and I've been pumping consistently. They have been holding up and I am loving them.

LOVE that these have the size measurement on the outer bevels so you can easily tell which size they are!

The willow is not working for me. I have only been able to get one ounce with a pumping session compared to 5 oz with the spectra. I tried a different flange size and this made no difference. I also tried different bras. Very disappointing especially for the price even with my insurance!

The Willow 360 pump was extremely painful even after trying many sessions and getting assistance from the mom coaches with sizing and other usage tips. I would not recommend this product to anyone and so far Willow has not assisted me with any even partial refund so I would also not buy from this company.
