Amazing
Color: 2pcs
This product is amazing. Works overnight. Could soften an elephant's hide, it’s that good.

Anti Crack Cream
Color: 2pcs
As a first time user of O’CHEAL Anti Crack Care Cream…Wasn’t too satisfied with this product! The Peach scent wasn’t as solid as the original. I had a difficult time pulling the cover off and the stick broke…making application really messy! Product did not live up to the advertisement!

Best Foot Cream I’ve Ever Used!
Item Package Quantity: 1
This is honestly the best foot cream I’ve ever used! My feet are incredibly smooth, and my heels look like they’ve never been cracked. I’ve struggled with dry heels before, and this made such a noticeable difference. Highly recommend!
