I bought this a year ago and used it for about six months under my electronic drums at home. I'm selling it due to moving. It will be shipped rolled up in the original box. This mat reduces vibrations to the floor when playing electronic drums. It absorbs vibrations thanks to its three-layer construction with thick materials. It also prevents scratches on the floor from the spikes of the kick pad and hi-hat pedal, even in rooms with hardwood floors. Please note that it does not completely eliminate vibrations. Size: Width 120cm, Depth 130cm, Thickness 0.8cm Material: Surface: Nylon, Back: Urethane foam Reference Price: ¥19,800
