I'm selling this because I bought it for practice but haven't used it at all. I've used it two or three times, and haven't used it much since then, so I think it's in good condition, but please refrain from purchasing if you are sensitive to such things. This is a drum training pad from VIC FIRTH. Single-sided. It's made of soft rubber with excellent soundproofing. Size: 12 inches. Vic Firth practice pad, with non-slip processing for excellent stability. - Brand: Vic Firth - Shape: Octagon - Surface: Practice pad - Back: Non-slip processing Thank you for looking.
