The Highlander Solid Fuel Hand Warmer is perfect for cold winter days when just a little bit of warmth can make a big bit of difference. The hand warmer is a sturdy, pocket sized case that is heated by burning a solid fuel stick inside. The case is well insulated so that the outside doesn't get too hot to touch and it is covered in felt to give it a warm, soft finish. To use, simply light one end of the fuel stick, place it inside the case and close the lid. It should then generate heat for up to 6 hours as the fuel stick slowly burns away. The Highlander Solid Fuel Hand Warmer is a very welcome companion whenever you're skiing, camping, fishing, walking and sailing - or even just sitting in the back of a cold, draughty car on a long, winter journey. It is supplied with a single solid fuel stick to get you started, so you will also need to purchase a packet of Highlander Hand Warmer Solid Fuel Sticks if you want to continue using it.
