How long does KoreSphere stay hot/cold?

KoreSphere is a stainless steel massage roller ball that is filled with a special cooling/thermal gel that eliminates pain on contact. When you place KoreSphere in a bowl of hot water for 20 minutes, you will activate the heat therapy. To activate cold therapy, just place KoreSphere in the freezer for a couple hours.

When you heat KoreSphere in hot water for 15 minutes, the massage roller ball will stay hot for around15 to 30 minutes. If you choose cooling relief, 2 hours in the freezer will result in up to 6 hours of cryotherapy cooling relief!

**Disclaimer - Do not use it for more than 20 minutes at a time. Also, if you’re going to remove the plastic handle, be sure to use KoreSphere against a surface like a wall or the floor - don’t hold it in your hand. We do not recommend gripping the hot/cold metal massage ball in your hand for an extended period of time.
