Thank you for viewing. This is an accessory that came with a musical instrument I purchased. I'm not sure how often it was used or how it was stored, but it appears to have some cracks, although I think it can still be used. • Adhesive: Strong (firm grip, typical of black rosin) • Tone: Dark and thick, with a particularly prominent low end • Response: Slightly heavy (not overly sharp on initial attack) • Recommended for: • Those whose bows tend to slip • Those whose sound thins out at low volumes • Use in winter or dry environments Notes: • Applying too much can make it feel gritty
