The Glorious Wood Wrist Rests are crafted from White Ash wood with a medium to coarse grain. The solid wood provides excellent support when using your gaming keyboard. Every rest is one-of-a-kind with a unique grain pattern. The wrist rests are coated with a unique polish that provides a smooth surface for sliding your palms around, and is resistant to erosion from sweat and oils. On the bottom of our wrist rests you will find non-slip rubber pads that prevent them from moving across various surfaces.
