Bobelock bow cases fit violin, viola, cello and bass bows comfortably. Bass bow cases are lined with wine or blue velour (green available in single violin size) and surrounded by a sturdy plywood shell. The covering on our bow cases is a tough pebble-grain vinyl that lasts for years. The violin/viola/cello bow cases easily fit all three sizes of bow and are designed to keep them from sliding around inside; very important for those delicate tips! Sturdy clasps keep the case closed even if dropped.
