Designed to rest gently on the top of the shoulders along the base of the neck, this moist heat heating pad is completely reusable and easy to wash. Unlike other pain relief products, our microwaveable heat pack requires no special covers and can be safely applied directly to skin or over clothing. Constructed with durable MediBeads that won't dry out or disintegrate, this microwave heat pad is odor- and dust-free and will not support bacteria or fungal growth unlike other grain and pellet products. Simply microwave our heat packs to enjoy clean, deeply penetrating moist heat - no need to add water.
