This is an aluminum panel in the Eurorack format for the NonLinear Circuits Sloth chaos module. This panel is made of aluminum with a reverse UV-printed textured Lexan decal adhered with a heavy-duty adhesive designed so that it won't curl or warp. Because the imagery is printed from the reverse side of the Lexan, then applied to the panel, it's extremely durable. Go get your turquiose on.
