Set of 8 Metal & Wood Mahjong Buttons

The button tiles measure 5/8” x 1/2” x 1/8”, they just barely hang in the small Linley measure. A cold enameled metal plaque is adhered to a rectangle of wood which is possibly bamboo. Seven shanks are plastic. The shank on the bamboo tile is metal. Good condition. In fact the protective plastic film was still on most of the buttons.
