    The shipping took a little bit but that’s a usps issue. The product is awesome. I was having issues with my supply so I decided to try this. It helped tremendously! I’d purchase the spray again because I don’t like rubbing product on my ns. I’d recommend this package to anyone!

    I love this product soooo much!! The only complaint I have is that I wish they came in little resealable baggies to keep the sizes organized easier. But I love this sooooo much! Thank you for doing what you do!

    This product is a nice starter kit especially for exclusive pumpers. As I progress of my pumping journey, my nipples changed size. Having the ruler and inserts helped me in finding the perfect size. I do not recommend the lube for myself though. It did not properly lubricate my flanges as well as regular coconut or olive oil would causing friction and pain. I do recommend the kit overall

    I exclusively pump and I love that I received multiple sizes of inserts to try. My nipple size has changed several times postpartum. Receiving multiple size inserts helped me not feel like I was wasting money or playing a guessing game. The healing spray makes pumping so much more comfortable. It has been a game changer!

    I waited for months for this! I was so excited to see it was finally back in stock. Worth the buy, 10 out of 10.
