    [This review was collected as part of a promotion.] Great addition to make pumping unique to anyone. Didn’t think I needed custom sizing until I tried and was pleasantly surprised by the better fit.

    A must if you are pumping

    Really loved this product instantly helped with me pumping pain. They work great in electric pumps. in manual pumps as well but they fall into the insert because the fanned out design, but honestly they still work and help. I was so grateful that these were in store and didn’t have to wait to get some shipped.

    I love that I can

    [This review was collected as part of a promotion.] I love that I can get all sizes. Specially since each breast needs a different flange size. It is more cost effective to buy the sizing kit if you need two sets that are different sizes.

    So comfy and pretty!

    I use the size 17 mm flange with my Spectra and have gotten better output! I do not have pain or ripped skin from suction. The edges of the flanges are like a flower and make it so much more comfy when removing the pumps, not to mention pretty!

    Cute and useful!

    I had no idea what the proper size flange is key for maximum output. My Spectra only had size 21 and 24 while the Willow kit put me on a size 17. After speaking with my lactation consultant, I learned the sizing kit was perfect for small girls like me!

    The sizing inserts are perfect for getting the right flange size! They are super comfortable. The best part is having a variety of sizes to try. This helped find the perfect fit. I highly recommend this product!

    Breast pump sizing kit

    This is my third baby and I was making it priority the third time around to have the correct size met for me. This kit made it incredibly easy, wish I would’ve done it sooner. Great product!

    Such a handy kit!

    This kit is so handy for a newly breastfeeding mom! My flange size changed throughout my first time breastfeeding so I anticipate that happening again with my second. It’ll be handy as I continue to breastfeed and need to adjust sizes. I also like having all the sizes in the kit so I can try out which one works best. I highly recommend this flange kit!
