This is the smaller brother of the fireplace simulator for your desktop. You can attach it to your keyring and use it to simulate firewood. It looks cool and you only have to blow over the wood to see the fire effects and hear the cracking sounds.
FireWood Pocket comes in black, grey or charcoal, at a size of 100 x 150 x 30 mm, powered by two LR44 batteries. Find it at JapanTrendShop at $27.
