This melts my heart and not my hands!
Keyboards these days can get really cold. Whether you’re typing up a memo in the office, or finishing that overdue assignment in class; typing can be a chilly business.
But you don’t have to be a survivalist to realise that there’s a simple and convenient way to warm our hands, and its right under our noses. Toast. Warm, toasty, toast. It’s the perfect size to cover your hands and easy to strap onwithout affecting your ability to type.
