These Ultra-Thin "Heater Cards" Provide 8 Hours of Instant Heat and Fit in Your Pocket.

You've tried clumsy disposable packets that die too soon. This is different; it's a set of two card-style electric heaters that use a 5000mAh rechargeable core to deliver instant warmth.

Forget the constant waste of single-use warmers and focus on a single, reliable source of heat that lasts all day.

With just the press of a button, you get instant, adjustable warmth for up to 8 hours, all from a device thinner than your wallet.
