Zincalloy catalyst hand warmer built for reliable, pocketready heat Key benefits Portable warmth on demand: Compact, lightweight design provides steady heat where and when you need it—no batteries or electricity required. Durable and finish: Made from zinc alloy and mirror polished for a smooth, textured surface that resists wear and maintains appearance over time. Efficient, even heating: Hollow design and a special heating catalyst generate heat that dissipates through the ventilation holes, delivering good thermal conductivity and a continuous, constant temperature. Clean, convenient refueling: Includes a leakproof fuel can that inserts into the oil filling port for fast refills without leakage—convenient and quick to use (no oil). Features Material: Zinc alloy construction for strength, heat resistance, and a refined finish. Design: Hollow body with ventilation holes to distribute heat evenly and maintain steady warmth. Fuel: Supplied leakproof fuel can fits the builtin oil filling port for safe, spill refilling. Size and portability: Mini, pocketable form factor—lightweight and compact for easy carry. Practical use scenarios Commuting and outdoor waiting: Keep in your coat or bag to stay warm during morning commutes, waits at bus stops, or outdoor lines. Travel and camping: Pocketsized heat source ideal for cold evenings on a campsite, hiking breaks, or travel in colder climates. Office or seated activities: Use at your desk or during outdoor events to maintain comfort without noisy or bulky heaters. What it solves Eliminates shortterm cold discomfort without cords or disposable warmers. Reduces mess and fuel spills with a leakproof refilling system. Provides reliable, consistent warmth thanks to efficient catalyst heating and good thermal conductivity. Care notes Use only the supplied fuel can and follow all safety and refilling instructions.
