Say goodbye to chilly hands thanks to this super-cute pair of Pusheen hand warmers. Each hand warmer is fashioned like the classic Pusheen Mermaid and is simple to use. To warm up - simply click the mermaid's metal disc and feel your hands get cosier in seconds. Even better - the hand warmers are reusable. Boil then simmer them for 5 minutes until the hand warmers go from hard to soft and can be used again.
