Hyper plastic foam Chassis dense semie rigid under which is arranged a non-slip sole in a kind of silicone or soft plastic, very effective on all media (glass, wood veneer, ...) and easily washable (glue as ;-) dust: do not just moving once on the desk! Above, a latex cushion shaped little ass covered with a synthetic liner that I believe to be washable! (See my video of unboxing on the tube under the ref. 14D50nJIAvM or "Wrist Speed Link LAX")
