Just as good as paraffin wax
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
I might prefer these socks over paraffin wax. They are comfy and very moisturizing. I use these socks once a week to keep the heels and soles of my feet moisturized between pedicures. I rinse with warm, soapy water then hang to dry. They are hard to walk in, but there's a saying printed in the socks that's says something to the effect of "take a break, stay off your feet" lol I love that as a reminder to put my feet up and relax

Love these!
Color: Pink & Beige, Size: Small(fits up to size 7)
Love these! As I write this review, I’m sitting in my recliner with these on. I have had other silicone socks in the past and would like to share a few of the things that I have learned. These fit great! The others were 2-3 sizes too big because you could not order a size. I wear a size 7 women’s shoe. I got the smaller size. I walked around my apartment in my old ones and they got kinda yucky. Now, I sit in my recliner, put them on and chill for a few hours. I now take them off and put in a ziplock bag so they stay nice and clean (no cat hair!). I use them once a week usually on Saturday or Sunday as I’m a working girl. Also, I use Auqaphor before I put them on and put cotton socks on after I’m finished. Your feet will be SO soft. This is not a one and done…I do this every week especially during sandal season! I know this was lengthy and I hope you got some tips.

Super fun, easy to use, and beautiful!
Color: Sparkling Pink
Love it! I can’t stop thinking of excuses to wear it just in my day-to-day life because I love how it looks so much. I put it on my cheekbones, nose, and collarbones, and I also put it on over my eyes like an eyeshadow and it worked really well for that too. It’s super easy to use and intuitive, you just roll it on. It didn’t bother my skin either, which some glitters do because I have sensitive skin. Comes off easily with water and a washcloth, although some of it hangs around and you have to take it off with makeup remover, but that’s no problem for me honestly. It does rub off a bit, so be prepared for whatever you wear with it to get a little glittery. Great product, recommend!

Great little roll-on stick, used it for stocking stuffers
Color: Dazzle
Love this roll-on sparkle glitter stick! Perfect for skin. If you need a hint of sparkle on your cheeks, even in your hair, the colors here are beautiful. This would be great for Halloween, parties, even get appropriate color for a formal celebration like a wedding. It is easy to apply, and lasts a long time.
