Lot of three sets of vintage mahjong tile beads and spacers for bracelets, brooches, or other crafts. AI-generated description says that "each set features exquisitely hand-carved rectangular beads made from polished Bos Taurus," though sets 2 and 3 look like butterscotch Bakelite to me. See photos for measurements.
Set 1: Double-drilled bone tiles (7) with 19 cream beads and 13 black beads with red and yellow detailing.
Set 2: Butterscotch set: One tile with brooch attachment and no holes; 6 double-drilled tiles.
Set 3: Set of 6 double-drilled tiles, one with remnants of an earlier bracelet still in the holes; 11 clear yellow beads; 12 black opaque beads.
75 beads in total.
