1cm scale black brushed cube made of tungsten carbide, plated with Titanium Aluminum Nitrile that has been laser etched. Tungsten carbide is extremally stretch resistant and has a very nice heft. (heavy)
I have sold thousands of scale cubes,
Most meteorite magazines and books have my scale objects in them.
I have been supplying, making, and customizing scale cubes and scale objects for over 10 years
