Thank you for viewing! This is a 3D-printed protective cover for the QUAD CORTEX. If you want a slightly different look from other products, please take a look! It can prevent scratches and sweat from getting on the main unit, and a guard has been added around the volume knob. The volume knob guard can also be removed, so please choose as you like. The screen part has a transparent cover that can be attached with magnets, and can be removed smoothly during operation. Color inversion is also possible, so please feel free to comment. Double-sided tape is attached to the back for adhesion to the main unit. * We will create and ship the item after purchase, as shown in the photos. * No discounts or dedicated listings.
