Great product to keep moisture in
Size: M (up to size 9)-Beige
These are so cool. I was skeptical at first. After an at home pedicure I put lotion on and keep these on for about a few hours. The moisture retention, and comfort and fit or absolutely amazing!

These work!
Size: M (up to size 9)-Beige
I’ve had dry cracked feet my whole life. Tried these last night with lotion from Trader Joe’s and literally overnight my feet are the softest they’ve ever been. I put a pair of socks over them and went to sleep with them on. Hard to walk around with all that slippery-ness but worth it! 10/10✨👌

A quality, glitzy little bottle of shine
Color: #07 Golden, Size: 0.17 Ounce (Pack of 1)
Lovely spray shimmer POWDER, really great for just spritzing on. The little bottle is adorable, easy to carry in your bag (has a little safety lid) and great for a little gift. It gives little puffs of glittery powder and it stays nicely, though I almost never perspire.
