KoreSphere is one of the most effective massage and recovery tools because of its versatility. Thanks to unique cooling/thermal gel at the core of the stainless steel massage roller ball, KoreShere has the power to deliver hot OR cold massage therapy, depending on what you desire.

For HOT massage therapy, place KoreSphere in a bowl of hot water (NOT boiling water) for just 15 minutes. Make sure to keep KoreSphere in hot water for no more than 15 minutes.

For COLD therapy, place the KoreSphere massage roller ball in the freezer for up to 2 hours. This will activate the cryotherapy that is much more effective and features way less mess than your average ice pack!

**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.
