The stainless - steel roller ball can maintain an ice - cold temperature. It comes with a comfortable, ergonomic rubber handle that provides a great grip. With its smooth rolling action, it offers both ice - pack type therapy and massaging relief. Once you freeze the stainless roller ball, it stays cold longer than regular ice and won't melt. You can easily roll it over your muscles to relieve pain. Cryotherapy, a well - known method, helps reduce post - exercise swelling and inflammation.

Using this cold ball roller is easy. First, put the stainless - steel roller ball in the freezer until it's ice - cold. Then, take it out and hold the rubber handle. Roll the cold ball gently over the areas of your body where you're feeling muscle pain, like your legs, arms, or back. You'll feel the coolness and the gentle massage working to relieve your discomfort. When you're done using it, just wipe it clean with a soft, dry cloth and store it in a cool, dry place. Make sure not to drop the roller ball as it could damage the stainless - steel part. Also, don't use it on broken or irritated skin.
