Remember to remove the massage ball from the holder, and remove the plastic before heating. Designed for comfort and effectiveness, the Himalayan Salt Ball Roller, complete with a convenient holder for seamless massages, is a must-have accessory for massage enthusiasts. Its ergonomic design fits perfectly in your hand, allowing you to effortlessly roll away tension and stress. Simply add a drop of your favorite massage oil to the salt ball for a smoother glide that nurtures your skin and enhances relaxation. Crafted from genuine Himalayan salt, each roller boasts unique mineral-rich properties that transfer to your skin as you use it. The gentle pressure and the soothing texture of the salt work in harmony, creating a spa-like experience in the comfort of your own space. Use: The Massage Ball can be easily warmed up in a microwave for 30 seconds, or on a skillet set on low heat. To ensure the perfect temperature, use one of our Warming Bowls (part #HSSL-MSW) with a 40-Watt bulb.
