Dissatisfied
Didn't like the socks at all. The silicone in them made my feet sweat and couldn't wiggle my toes at all.
Gloves were okay, received them with holes between the fingers, only able to wear each twice.

too small
I saw these and instantly thought they would be amazing! I was hoping for just that. I received them today and tried them right away. I love the gel feel but im not really liking the way they kept rolling off. They're a bit too small id say and when walking they roll off from the back. I didnt think my foot was other than average? Maybe? Im a size 7 in women's shoes.

Super Awesome
I have the driest feet, my mom did too so I should have known that I would inherit it as an adult myself. My toes literally crack and split open from dry skin, I call them fissures. They really hurt. Last night I used my cheese grater foot file gently on my heels and calloused parts, and then applied liberal lotion, and wore those squishy socks all night. I woke up to the most moisturized youthful feet I’ve ever seen attached to my body! Wow these totally work!!! I even slept better than I have in a very long time. I’m very pleased. These did exactly what I hoped they would do.

Amazing!

Wow, what to say about this glitter spray. If you want to cosplay as a Twilight vampire, buy this spray. Haha. I’m not even kidding. I got this spray for going to a concert - one of the few occasions I go all out in getting dressed up. I LOVE sparkly/shiny/glittery things, so this spray seemed like an obvious choice. I did a very light, quick spray over my face/neck and OH. MY. GOSH. “I look like a vampire from Twilight.” My first thought/words after looking at myself in the mirror. My mom got a pretty big kick out of it and couldn’t stop giggling because that’s all she could think about afterward whenever she looked at me.
I expected this spray to be something I’d have to spray multiple coats of, but absolutely not. This is a one and done spray. The glitter is HIGHLY CONCENTRATED. Very, very sparkly with multifaceted color sparkles - not just silver. I got some on my hair when I sprayed myself, so I went ahead and sprayed the back of my hair too. Didn’t put any kind of film or anything in my hair. I was still able to brush it and do everything else as if there was nothing in my hair. At the end of the night, it washed off very easily.
I will say as a pointer, unless you want your hair or clothes to have glitter on them as well, then you should apply this glitter spray BEFORE you get dressed and you should wear a shower cap/bag/something to cover your hair while applying. However, it works just fine on your hair and clothes as well - no staining or damage.
The can looks small BUT with how little you have to use, one can will go a very long way. I could go to 10 concerts and I’m pretty sure this can would still be more than half full.
HIGHLY RECOMMEND!
