The complete endpin solution which works like magic! Using an adhesive-like surface, the Pinstop will stick reliably to almost any floor–vinyl, tile, wood, stone, finished concrete, carpet–even grass! The innovative adhesive cleans easily with soap and water and stays super sticky time after time. It’s small (2″ x 3″), lightweight and conveniently fits into a pocket or music folder. It’s made of recycled plastic and fits any cello or double bass.
