This is a floor tom from the Pearl Soundcheck Series. I'm not very knowledgeable, but the inner diameter is 36cm, so I believe it's a 14-inch. It's a used item, but I think it's relatively clean. The condition is as shown in the photos. Please refrain from purchasing if you are overly concerned about minor imperfections. Diameter: Approximately 35cm (playing surface) Height: Approximately 32cm (from the bottom to the top edge) - Brand: Pearl - Model: Soundcheck Series - Included: 3 stands Thank you for looking.
