Horrible smell
Bought this to use on my hair smells so bad. I can’t even use it. The consistency is not my favorite. The glitter is too fine. Will look for a better product next time. Would definitely not buy again

Great hair/body spray
Sprays on easily and evenly haven’t had any issues with clogging. Has no smell and great even consistent sparkle. This took awhile to be delivered but overall happy with this purchase. Did not wash off in pool but washes off in shower easily.

So excited for results, feels like it’s working!
Size: Medium, Unit Count: 4
First time trying them right now as delivered today. Originally thought was supposed to wear all night but glad to find out 30 minutes just because my dog sleeps on my feet over my sheets! These silicone socks feel great and I trim my toe nails short enough they seem very durable and unlikely to rip like the pic review shows. I am confident my feet and heels will much smoother after first time wearing! I do have acrylic nails so I will be careful
Putting the silicone socks on and off. Just as easy as the video the spread the lotion inside the socks and rub it around, mess free!!

Actually, better than I expected!
Size: Medium, Unit Count: 4
These are better than what I was expecting based on the reviews. I do put them on carefully because someone said you can’t tear them so I’m careful putting them on, but they almost don’t feel like you’re wearing anything as long as you don’t put them too tight on your toes. I can put lotion on my feet and I know it has to soak in because there’s no place else for it to go like socks or my bed.
