Pumping mamas, if you've ever struggled with ill-fitting flanges, this 5-size insert set is your new best friend! You get 10 pieces total - two of each size (13mm, 15mm, 17mm, 19mm, and 21mm) so you can find your perfect fit as your body changes throughout your breastfeeding journey. Made from premium medical-grade silicone that's BPA-free and super soft against sensitive skin, these inserts make pumping so much more comfortable. They're compatible with most 24mm shields and work beautifully with Momcozy S12 Pro, S9 Pro, S12, S9, and similar wearable pumps from TSRETE and other brands. The set saves you the hassle and expense of buying multiple flange sizes separately - just try different sizes until you find the one that creates the best seal without discomfort. Using coconut oil or nipple cream with these can reduce friction even further for those marathon pumping sessions. Since nipple size can change throughout the day and over time, having multiple options ensures you always have a comfortable fit. The inserts are easy to clean and maintain - just wash with warm soapy water after each use. They're also great to have on hand as backups when your original parts wear out. Seriously, if pumping has been uncomfortable or inefficient for you, the right flange size makes all the difference in comfort and milk output. This affordable set takes the guesswork out of finding your perfect fit!
