This colour changing heat mat from Wahl is a useful accessory to have if you own a pair of hair straighteners or curling tongs. It protects surfaces from heated appliances and warns you when they're still hot. The colour changing mat can withstand temperatures up to 300ºC, and this silicone mat changes colour to let you know when it is hot, indicating whether your appliance is still switched on or not. This helps to prevent you leaving your appliances on by accident when you're no longer using them. It is a non-slip mat, making it an ideal addition to your dressing table or workstation.
