This is a "pet cooler board" that utilizes the evaporative cooling effect of water. To use it, simply soak the sheet installed on the back of the stainless steel plate with water. ・There are stains on the sheet that won't come off, but I bleached it with OxiClean. That's why it's wrinkled. ・The included nylon cloth to be placed on top of the stainless steel plate has stains that won't come off, but I bleached it with OxiClean. I will include it if you don't need it. (Replacement sheets may be available for purchase.) Board Size: Width 50cm x Depth 35cm x Height 2.3cm
