YAMAHA Yamaha Drum Mat DM1314 I purchased this with a drum set, but I'm selling it because I don't use it. I will fold it for packaging when shipping. The following is the manufacturer's description: Size: 1,300mm x 1,400mm The outer circumference of the mat is sewn with bias tape for high durability. The back of the mat has a non-slip resin treatment for stable playing. A calm gray color that matches the room. Fire-retardant specification (Japan Fire Retardant Association registered)
