The Fisura "Fucking Cold" hand warmer is the ideal pocket-sized thermal bag for those who want to combat low temperatures effectively and with a touch of bold humor. Featuring a compact size of 10 x 6.5 cm and a light weight of 70 g, this thermal bag made of sodium acetate, water, and PVP heats up to 57 ºC immediately after bending the inner metal disc. Its reusable structure allows it to be restored to its original liquid state by boiling the product wrapped in a cloth for 5 minutes in very hot water. The irreverent design with the printed message makes this warmer the perfect companion to carry in your jacket during winter hikes, daily commutes, or trips to snowy destinations.
