Easy-to-install metal fan heater guard, designed to stay cool for improved safety. - Product Name: Fan Heater Guard - Features: Easy to install, stays cool - Materials: Metal, silicone rubber - Design: Slit structure There is some discoloration on the rubber parts due to use, but I believe it does not affect functionality. It has been used for several years, so there is a sense of use. The box is also tattered. Thank you for looking.
