Nuliie10PCS Flange Sizing Kit 13/15/17/19/21mm for 24mm Flange/Shield of Most Pumps, Silicone Flanges Insert for Momcozy/Spectra Electric Breast Pumps, Pumping Essential Kit for Moms

I had no idea how much the wrong flange size was affecting my pumping sessions until I tried this kit. The Nuliie Flange Sizing Kit made it incredibly easy to find the perfect fit for my needs. The variety of sizes (13, 15, 17, 19, and 21mm) allowed me to experiment and discover which one provided the most comfort and efficiency.The silicone inserts are soft yet durable, and they fit seamlessly into my 24mm flanges. Cleaning is a breeze, and I appreciate that they’re BPA-free. The included nipple ruler was a thoughtful addition, making it straightforward to measure and select the right size.Since using the correct size insert, I’ve noticed a significant improvement in milk output and a reduction in discomfort. This kit is a must-have for any pumping mom looking to optimize their experience.

This is extremely helpful to determine what size flange you need. It simplifies the process and even offers a way to sample if you feel like you are in between sizes. I have gifted this to many people for baby showers! As a first time mom, I had absolutely no idea what I was doing and this saved me a lot of trips to a lactation consultant (and saved me the pain of having an incorrect size!). An absolute MUST buy for a new mom on her breastfeeding journey.

If you plan to pump or breastfeed I highly recommend buying this or putting it on your registry before baby is born. The difference between having a fitting flange and just using the one that comes with your pump is night and day. I struggled so much with my last child and I wish I had done this sooner.

Regular pumps will rarely come in the size that you need. If you are purchasing a pump for yourself or someone else you HAVE TO buy these inserts so you can figure out what size flange you actually need to avoid hurting your nipples. Buy them. You absolutely will not regret it.

Works well. Make sure you lubricate them before pumping or the silicone feels sticky and hurts. My own fault, I didn't realize I couldn't insert them into my 21mm flanges. I pulled out the 28mm that came with the pump and was able to insert these, making the 28s become 19s. I do notice more swelling during pumps and sometimes have to pause to size up, but this could be just me.

Worked great for getting the correct size in my spectra pump. I thought I just had a low supply but one using the correct flange size u have seen a huge difference. Comes with a few extras like the cleaning brush and sizing guide. Worth the money if you are serious about pumping!

If you are a first time mom it’s a YES!!! 100% would recommend had my wife known about this with our first she would have enjoyed pumping way more. The comfort of having your right fit is chefs kiss!!! Those were her words. She said all pumps should come with these because not everyone has a nipples like hotdogs 😂

This was the perfect starter kit for figuring out what size flange I needed for pumping. One of my labor and delivery nurses shared the link with me and I’ve never made a purchase faster in my life. It made a HUGE difference in my pumping experience.
