Thank you for your interest in our product. I created a platform for attaching Velcro because I don't like the bottom of my effectors getting sticky from Velcro (hook-and-loop fasteners). By attaching this product to your effector with silicone tape or easily removable double-sided tape, you can mount it on your effector board without making it sticky. 【Target Products】 ZOOM's ・MULTISTOMP MS-50G+ ・MULTISTOMP MS-60B+ ・MULTISTOMP MS-80IR+ This is a mounting base and a set of 4 switch caps (switch hats) for these products. ※Effector body is not included. 【Material】 Made of PLA (black / red and green only for switch hats) We check the products during production, but Due to the nature of 3D printers, there may be minor burrs, layer lines, stringing, and support material marks. Please understand. 【Other】 Please purchase after you are satisfied to avoid any problems after purchase. You can purchase immediately without any inquiries. Thank you for your consideration. #guitar #bass #multieffector #ZOOM #MULTISTOMP #MS50G #MS60B #multistomp #multieffector #pedalboard
