The NEW gLOVE Treat Mitt is sized unisex medium hands. See sizing below. Simply place the gLOVE Treat Mitt into a microwave for 2 minutes in 30-second intervals until the patented thermochromic indicator turns bright red. Wait until the heart shaped patch returns to a gray color and insert your hand. Then sit back and relax for 15 minutes as gLOVE Treat's exclusive mixture of essential oils and paraffin wax ease the pain from your joints and moisturizes dry and cracked skin. Each gLOVE Treat Mitt can be used up to 4 times! For best results, treat yourself once a week for dry, chapped and sore hands.
