Reliable, Long-Lasting Warmth You Can Trust

UniHeat warmers use a safe, gradual slow-release heat profile that won’t spike and cook your plants or animals like ordinary hand warmers. Each pack activates with air, with no shaking or microwaving needed, and holds a steady surface temperature of roughly 100°F (38°C) for the full rated duration. The ingredients are non-toxic and can be disposed of with your regular household trash.
