Each piece with real Mother of Pearl inserts which have been separated by the 1930s Schreiber Hiller patented design element referred to as tank tracks. Machine-age style in design. The condition of all pieces is very good, needs a bit of polishing on reverse side where it shows some wear from being gently worn against the skin. Jewelry box not included.
