Review: Breastfeeding necessity - I’m so glad I found this flange sizing kit—it has made a huge difference in my pumping experience. The silicone is really high-quality, soft but durable, and super easy to clean, which is a must when you’re using something this often. I love that it comes with both a sizing chart and a conversion chart. It took all the guesswork out of figuring out the right fit, and having everything included made the process so much less stressful. The little cleaning tool it comes with is also such a thoughtful bonus—it makes keeping everything sanitary quick and easy. The biggest difference for me has been comfort and output. Since using the correct size, I’ve noticed a significant increase in my milk supply and way less pain while pumping. It’s honestly been a game changer. If you’re breastfeeding or pumping and unsure about your flange size, I highly recommend this kit. It’s simple, effective, and made a noticeable difference for me right away.
Review: I recommend this size kit to ANY new mom! - I recommend this kit for ANY new mom. This flange sizing kit was super helpful and made figuring out the correct size so much easier. I love that it includes multiple sizes all in one kit, especially for new breastfeeding moms trying to get the best fit for comfort and output. The material feels durable, the measurements seem accurate, and it worked well with my pump setup. Definitely a useful little tool to have before spending money on multiple flange inserts that may not fit correctly.

### ⭐⭐⭐⭐⭐ Breastfeeding necessity
*by G***I on April 15, 2026*

### ⭐⭐⭐⭐⭐ No-frills variety pack gives you plenty of options
*by T***U on July 12, 2025*

Summary: it’s exactly as advertised. You get a variety of flange inserts to test, a very handy brush to wash them, and a nipple guide to measure. Easy, straightforward, can’t go wrong buying the variety pack. More detail: it’s packaged well, each set of flange inserts comes in its own plastic packaging in the box. On each insert, the size is printed on the rim of it, so it’s fairly easy to see what size you’re working with. The included brush makes it much easier to clean, especially if you get bits of milk stuck around the edges, which is pretty common for me. It’s difficult to get it fully clean when using a traditional bottle brush, but the included brush is made of a soft material that really gets the milk off. It fit perfectly in my spectra flanges, and fit pretty decently in my Mandela ones- it just needed a little bit more finagling to get a flush fit. This was a good way to test out a variety of different sizes quickly. Tip: the silicone can stick a little, and create friction on your sensitive areas. A dab of coconut oil on your nipples before you pump, and you won’t have this problem. You can also apply the oil directly to the flange insert, but it gets a bit messy. Putting it on your skin is just as effective, without making the flange overly greasy.
