    Best pads ever!!

    Please never change anything you’re doing! These are hands down the best pads I’ve ever used. They stay in place, don’t bunch up, and are so soft it feels like I’m just wearing underwear! I’m obsessed 😝🫶

    Super pad experience as a freshman college student

    I was give the flex pads at my college when they did an event. I'm using this for the second time and there most softs and most comfortable pads ever. I'm a type of person that has cramps when I'm on period and with this pad I don't feel bloated or cramps that much.

    The Cadillac of Pads (4.5/5 stars)

    I have not used a pad since I got first my period over 25 years ago. I always found other pads to be like scratchy diapers.

    I bought these right before my surgery because I could only use pads after it for a few weeks.

    This pad is almost perfect. It is extremely soft to the touch, thin, and lightweight. You do not even notice you're wearing it. Seriously. It would be 100% perfect if there was a bit more adhesive closer to the ends of the pads, and more on the wings too. I am not even mad I have left over pads from my surgery. I know they won't go to waste.

    If I was forced to only ever use pads, I would always choose this pad. It is truly the cadillac of pads.

    These are the best pads ever.

    I’ve never wore a pad that has been so soft & comfortable. It genuinely makes me happy when i’m on my period to have something so soft & comfy to wear. So many other brands’ pads have harsh chemicals in them as well & I love that these are safe!
