This is a fantastic set of old dental tools. There are tiny heads with drills, pins, needles etc… there are several different sizes of tiny drill bits. There is a handle that I believe the pieces fit into. There are also several small drills that don’t fit into the toll that is included. There is a section that is sealed, that seems to have some small white strings of some type under the wax paper. This is quite a full set. It is marked Kerr on the box. It is 10" across, 4 1/2" wide and 1/2" tall. Dates to about the 1930’s.
