The Whitby Hand Warmer is a sleek tool that produces radiant heat without the flame, allowing you to warm your hands quickly and easily on the coldest of days. It generates heat quickly and effectively via a catalytic burner unit which usually lasts for 90 uses. This reusable hand warmer is environmentally friendly and is more effective than using a conventional warmer. Its compact profile means you can carry it around with you wherever your adventures take you.\'Flameless\' catalytic warmerBurn Time - 6 or 12 hours depending on fillBurner lifetime of 90 burns (assuming 12 hour burn)Protective fleece bagFilling cupLighter fluid not included
