  • Made Pumping So Much More Comfortable - Highly Recommend
Size: 10PCS 13/15/17/19/21mm Color: Pink
These are great! I thought pumping was going to be the easy part of nursing... but there is a lot I didn't know, and having the right flang size is SOOOO IMPORTANT! I liked that this kit came with the measurement as well as so many options for flanges (even though you really only need the size you are) - it saved me time (and money) ordering it all separate and made pumping so much more comfortable. Putting a little coconut oil on the pump/flang also helps a ton to make the process more comfortable. ... show more

Size: 10PCS 13/15/17/19/21mm Color: Pink
Loved my kit! Came with two of each size, which was super helpful! Sizer was easy to use, and included sponge brush has been an instant favorite, ended up keeping it with my travel pump and a bottle of soap. Fits my spectra and my Medela, easy to install and remove.

  • Worth It
Size: 10PCS 13/15/17/19/21mm Color: Pink
I wish I wouldn’t have waited so long to get this. Having the proper flange inserts in my pump has greatly increased my comfort while pumping, reduced trauma, and increased the ease of milk output. The measuring tool comes with easy instructions, and the silicone inserts are marked on the sides with which size they are. The inserts fit in the standard 24mm flanges that come with pumps. I do find it takes a little scooting and work to put the inserts in, but they stay firmly secured while pumping. I subtracted one star because one of the silicone inserts has a very small tear at the bottom after a few weeks of use. I’m watching it carefully because I don’t want pieces to tear off, but so far it seems fine and doesn’t affect the function of the insert. ... show more

Size: 10PCS 13/15/17/19/21mm Color: Pink
This was a great and easy quick fix for my pumping problem. I run as a size 19 flange and most pumps don’t come in that size so it was causing me some irritation when pumping. I was recommended these flange inserts by my lactation consultant and they worked perfectly. Easy to install on any pump, we have 3 different brands on of pumps (mom cozy, spectra, and Elvie) and it fit all of them. They are silicone, easy to clean. Definitely would recommend to other moms struggling with proper flange sizes. ... show more

Game changer first time mom here and these flanges has made pumping feel way better. They are very comfortable! Only thing I didn’t receive is the bottle washer, but I’m not too concerned about it I really just needed the flanges and the ruler.
