Instant Hot Multi-use Warmer 10" Round. Instant Hot Packs - Multi-Use Round 10" This is our 10" round Instant Multi-Use Warmer. Press its internal button and the pack instantly begins to warm up! As the liquid gel turns to a crystallized form, it releases warmth. Massage the pack as it heats to ensure it stays pliable. As it cools, it will harden into the shape where it was applied. The pack is re-useable. When it is cool, drop it into hot water to return it to its liquid gel form. When all the crystals are gone, the pack can be used again or stored to provide instant heat whenever needed time and time again.
Makes a great pet bed or other smaller area warmer!
