This is a clear violet cover for the Quad Cortex, made from 2mm thick acrylic. It may appear slightly blue in the image, but the actual color is a vibrant purple. The material is transparent, so the LED lights of the footswitches are visible even when the cover is installed. A cleaning cloth and transparent double-sided tape that leaves no residue are included. A set of a colorless, transparent lid and hinges is also available for an additional 500 yen. Please comment before purchasing to change the price. [Inspection and Exchange Policy] The product will generally be delivered with the protective film attached, but occasionally, laser-induced hazing that is not visible through the film may occur. In the unlikely event that a defect is found after removing the film, we will exchange the product as an initial defect, so please contact us before giving a rating.
