Blanks are made of printed circuit board material and they are 1.6mm thick(0.063″). The pure black sides can have slight imperfections because of the manufacturing process. Note, the 2hp blank is not black on the reverse graphic side.
The 2hp and 4hp blanks designs are based on a Turkish carpet motif representing ram horns(boynuz): a symbol of power.
The 3hp and 6hp blanks are designed using the hilbert curve fractal.
