This is a clear blue Quad Cortex cover made from 2mm thick acrylic. The transparent material allows you to see the LED lights on the footswitches 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 so I can adjust the price. [Inspection and Replacement] We generally ship the product with the protective film attached, but occasionally, there may be laser-induced hazing that is not visible through the film. If you find any defects after removing the film, we will replace the item as an initial defect. Please contact us before rating the product.
