Vintage mini Chess set Unsure if chess pieces are made of bone. I used a hot needle to check the bottom of one of the pieces and it didn’t burn so I don’t think there plastic or wood. Also under magnification they don’t have seems like plastic would have. Board Made of wood and material I’m unsure of. 15cm x 15cm wide 1.5cm tall Chess pieces 15mm tall 20mm with pin End wood pieces slide open to reveal hidden chess pieces Metal latches hold it closed Chess board sits slightly raised as hinges are slightly tight ( one side sits 1mm to 2mm slightly higher than the other side) Brass hinges One side of the board when closed has a few scratches on it Hinges slightly tarnished due to age
