Purchased three years ago, used for about two months indoors with an electronic drum set, but the drums themselves were hardly used during that time. It has been stored at home since then. The stripes in the photos are due to the lighting, but there is no discoloration. No pets, no smokers. There are no noticeable scratches or stains, but please understand that this is a used item before purchasing. It will be rolled up, wrapped in bubble wrap and packing tape, and shipped. This gray drum mat with the YAMAHA logo is made of fleece material, providing a comfortable playing environment. ◆ Electronic Drum Set Mat ◆ The outer edge 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 (registered with the Japan Fire Retardant Association) ■ Specifications ■ Recommended models: DTX400 series, DTX500K/520K/540K, DTX502 series, DTX700 series External dimensions: (Width) 1300 x (Height) 8 x (Depth) 1400mm Weight: 2.3kg [DM1314] - Brand: YAMAHA - Color: Gray - Type: Drum Mat - Design: With logo - Material: Fleece - Shape: Rectangle - Edging: Black edging Thank you for viewing.
