These tiles are so fun to play with that I had to get them in two colors but now I need to scale back. Set includes 160 tiles, 3 dice, 100 chips, a bettor guide and 4 reference cards. They are 1.41 x 0.98 x 0.47 inches and made from dense dual-color acrylic with light blue backs. Complete 160 American set with 36 dots; 36 band, 36 cracks, 12 dragons, 16 winds, 8 flowers, 10 jokers, and 6 blank spares. Nice mahjong tile bag is included.
