This is a Roland V-Drums (electronic drum) setting mat. The current retail price at musical instrument stores is 19,800 yen (tax included). The back has some marks and creases from the drum legs (as shown in the photos), but I think it won't affect actual use. I'm selling this because I got rid of my electronic drums. I will fold it up and package it for shipping. ■ External dimensions: 1,200 (W) x 1,300 (D) x 8 (H) mm ■ Weight: 2.1 kg Thank you for looking.
