This is a soundproof mat. The size is 160cm x 200cm. It's designed as an electronic drum mat, but can also be used for soundproofing for games, etc. It's a no-brand product, but the quality is assured. The surface is nylon and the back is urethane foam, so it adheres to the floor and won't slip. The surface is looped, so kick pedals won't slip due to the Velcro effect. Shipping is included, but Hokkaido, Okinawa, and other remote islands are excluded.
