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✨👌

Awesome bully sticks!
Patrick, my Border Collie, gets a 12 inch bully stick once or twice a week. He absolutely loves bully sticks more than any other treat, but I don’t! They all stink and cost a lot of money! But these Bully and Bones didn’t stink at all. So far, they’ve lasted twice as long as other bully sticks I have bought in the past. Very nice product, I’ll be buying more.

Golden Retriever Approved!
My 8-year-old golden retriever LOVES these bully sticks! And it makes me very happy to see how much joy she gets from them. They last a long long time, and of all the brands I've tried, these are hands down the best quality and best overall value. I also wanted to point out that this brand doesn't smell bad at all. Some of the other brands I've given her were a little stinky. She didn't care, but I really appreciate that these truly have no odor.
