Facial Cooling Massage Stick for Skin Care - Anti-Aging Ice Roller & Cosmetic Cooling Tool | Perfect for Puffiness Relief, Post-Workout Recovery & Summer Skin Refreshment

I've seen this from a Korean beauty show and wanted to try it out, and found this on Amazon.When I received it I was surprised since it was smaller than I thought, but it works great. (fits in one hand)I've tried leaving it in the freezer overnight and did not have a problem so far. (They only say you have to put it in the freezer for 1.5-2hrs to get 1hr coolness) The device stayed cool for at lest 20mins when I've used it before applying makeup for work. (I didn't have more time to use it)It did seem like it was getting warm in the first 5 mins, but after I set it aside to apply lotion, it got it's cool back. I'm assuming it felt warm because my face was so warm. It was great to do a quick face-neck massage and cool down my eye puffs.Will purchase again as a gift!
