Great for your skin [SEP] Omg these are wonderful. I used to rub ice over my face in the morning years ago. This is much better. It’s nice to have 4 to keto cold but I have not had to use more than one at a time. They stay cold for with a while. When it feels like it isn’t cold, I roll it a little with my finger and then it’s fine. This is a fantastic tool to use in the morning especially if you have puffy eyes. I like using it before I put on make up. At night I will sometimes use it after I put my serums  and moisturizer on. It’s very relaxing.
