This is a solid brass guitar slide, hand-crafted in the USA by master jeweler Ron Hall. This is an adjustable style brass slide formed from a rolled sheet, so that you can adjust it by bending to fit your finger. The word "HOBO" has been stamped on one side of the slide, in honor of the traveling workers who could have fashioned just this sort of slide for themselves back in the day. These slides are 2 inches long and adjustable to most any size finger.
