This is a 3D-printed protective cover for the QUAD CORTEX. If you want a slightly different look from other products, this is for you! It prevents 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, allowing for smooth removal during operation. You can also create your favorite one with a combination of turquoise and yellow! Please tell us the pattern in the transaction message after purchase. The yellow part glows in response to UV light. Double-sided tape is attached to the back for adhesion to the main unit. * We will create and ship the item shown in the photo after purchase. * No discounts or dedicated listings.
