These uniquely shaped "bobs" are all on 1/8" mandrel for use with miniature tools to help you buff & polish in tight corners & other hard to reach places.

For the best results, use with top quality Dico buffing compounds sold separately. 1/4" mandrel mounted. Contains four medium density bobs in assorted shapes.
