OUHOE Disposable Hand Warmer, Up to 10 Hours, Portable and Long-Lasting Cold-Resistant Winter Hand Warmer, Heat Therapy Hand Warmer Pads, 2pcs

Ingredients：Iron powder, activated carbon, superabsorbent polymer OUHOE Disposable Hand Warmer utilizes a core heating material blend of precisely proportioned iron powder, activated carbon, and superabsorbent polymer to create an intelligent oxygen-controlled heating system. This design effectively prevents rapid oxygen permeation that could trigger combustion hazards while avoiding the awkwardness of insufficient oxygen permeation causing inadequate warmth, delivering dual assurance of safety and heating performance. The usage steps are remarkably foolproof: Step 1: Wash hands with warm water (activates optimal heating performance). Step 2: Remove the warmer from packaging, place it in the palm of one hand, and gently cover it with the other hand. Within minutes, you'll feel gentle warmth radiating from within, lasting up to 10 hours. From morning commutes to late-night work sessions, it provides continuous warmth for your hands. Its portability is unmatched: Each compact warmer fits easily in pockets, gloves, or even your palm. Whether hiking outdoors, waiting for transit, or typing away at the office, it becomes your secret weapon against the cold. The “value pack” design with 2 pieces per bag ensures you can refill your warmth anytime, anywhere, completely eliminating the discomfort of cold hands and feet in winter. It's an essential warming tool for those who feel the cold, perfect for winter outings and daily office use.
