Heat packs provide hand warmth in cold conditions
Simply tear open a pack of hand warmers and expose to air; the heat packs warm up in just 10 minutes. Work great in gloves and provide 8+ hours of warm (137º) controlled heat. Warmers can be stored in an air-tight container for use across multiple days. Actual warmer measures 2"W x 3-1/2"L. Pkg. of 10 pairs. Imported.
