Always popular Mah Jong bracelet features Bakelite playing pieces. These vintage pieces are strung on elastic with green bead spacers as shown. This is a book piece and similar examples can be seen on page 107 of "Collecting Art Plastic Jewelry" by Leigh Leshner (2005). This one is unique in that all of the tiles are similar; that is not usually the case so someone went to a lot of trouble to find tiles that match. Great condition, fits comfortably because of the elastic.
