About this item
- Drug-free Whole Body Relief: There’s no limit to the uses of our lava sand microwavable heating pad. For neck, shoulder, and back pain, period cramps, joint stiffness, or cysts, use warm over the affected areas. Use frozen for sports injuries, swelling, or acute pain. Melt away stress, ease tense muscles, and warm cold feet – you get the idea!
- Dual Hot/Cold Action: Thanks to lava sand’s excellent responsiveness to hot and cold, you can use the sand bag as an ice pack as well as a back, neck, and shoulder heating pad. Microwavable and freezable, it’s ready within 1.5 to 2.5 minutes in the microwave or when frozen for a couple of hours.
- Soothing 4-pound Weight: Combining the healing effects of compression and thermotherapy, our heat pack has a penetrative effect that targets structures deep under your skin. The dense weight provides pressure to aching body parts, aiming for instant relief while boosting permanent recovery.
- Superior Heat Retention: Ultra-rare locally mined lava sand filling from Utah, USA, makes our hot pack for pain relief stand out from the rest. Releasing heat much slower and for longer than traditional filling materials once microwaved, its lasting action is complemented by the stitched chamber design that keeps the sand in place for even heat distribution.
- Life-Time & Convenient Design: Easy to use, maintain, and carry, with the 8x12 inch dimensions providing enough coverage without adding unnecessary bulk, our warm compress can be used on the go. To clean, wash by hand or in the top rack of your dishwasher. The lava sand will last you a lifetime.
- Weighted for Impact: Weighs 4 lbs and is very heavy—designed for deep pressure relief. Not suitable for weak or elderly users; ideal for intense soothing and relaxation.
