Hand Warmers

Hand warmers are essential to staying warm in the cold winters coming up. Our hand warmers use a less toxic material than most commercial brands, as well as a fun method of activation. To ensure the best user experience, we use thick, sturdy plastics on the outside, and thinner plastics on the inside. The reaction happens when the user squeezes the inner water pouch, and the calcium carbonate (CaCO3) reacts to the water, crystalizing, and producing long-lasting heat and a few byproducts.
