This highly adhesive mouse pad stays firmly attached to your desk. The countless air bubbles in the PVC (poly) foam backing act as suction cups, providing a firm grip that won't slip even with your finger. *Only works on smooth steel surfaces. It won't stick to cloth or concrete. The non-adhesive surface doesn't stick to the surface, so it won't slip off. It stays firmly attached to the surface, even after repeated removal. If the surface becomes dirty, simply wipe it with a damp cloth to restore its adhesive power. *The base material will absorb moisture from damp cloths, so please allow it to dry thoroughly before use. It's compatible with laser, optical, blue LED, and IR sensor mice. The irregularly textured surface ensures precise mouse operation. It adheres perfectly to the entire back, preventing warping over time. Color: Blue Size: W150 x D180 x H1.2mm Weight: 24g
