Using this massage ball roller is super easy. You can hold it in your hand and roll it over the areas of your body that feel tense, like your back, shoulders, or legs. You can use it dry or dampen it slightly if you prefer. When using it, don't apply too much pressure at once. Start gently and gradually increase the force according to your comfort level. As for maintenance, after each use, wipe it clean with a dry cloth. Keep it in a dry place away from direct sunlight. This will help keep the ball in good condition and ensure it lasts for a long time.
