These are Pearl's mesh drumheads for quiet practice. [Brand New, Unused] The Muffle Heads are 8-inch and 12-inch. They have never been used, but please refrain from purchasing if you are not comfortable with used items due to the long storage period. [No noticeable scratches or stains] Sponges are attached to the cymbals, hi-hat top, and hi-hat mute. I think they are clean because they haven't been used much.
