UST Reusable Hand Warmer
A great replacement for single-use disposable heaters, the UST Reusable Hand Warmer provides up to 130 degrees F of heat in just 15 seconds and keeps warm for up to 2 hours.
Perfect for cold-weather hunting, skiing, and treks through the snow, this easy-to-use temporary warming tool has a sodium acetate and water solution that begins heating by bending the metal activation disk inside the warmer.
After the disk clicks, massage hand warmer until the liquid is completely crystallized. Insulate the hand warmer in a towel or cloth material for longer lasting heat.
When the heat runs out, this cost effective, reusable hand warmer can be re-activated with boiling water.
- Bring a pot of boiling water to a slow simmer and place in the hand warmer

- Remove hand warmer and allow to cool to room temperature before next use
- Measures 4.13 x 2.95 x 0.79 inches
- Weighs 2.29 ounces
- Backed by a two-year manufacturer's limited warranty
