Here on ze Dark Side of ze Moon, what we use to move our Komputer Mice around on are called Mauspads. Just one Millimetre thick, it is highly ergonomic und works with both Optical and Kugelmice.
The Iron Sky mousepad has a print of a fleet of nazi saucers approaching from the Moon. It’s very thin (less than 1mm) and has a durable, slightly textured plastic surface that feels nice under a mouse. We actually use these ourselves and we’re pretty darn picky when it comes to anything to do with mice.
Protip: Spread a few drops of water on the bottom of the mousepad and it will stick to the table like a suction cup.
