Have fun playing with wooden domino parts! Parts A: 15 pieces Parts B: 15 pieces Parts C: 15 pieces - Material: Wood - Uses: Domino toppling and track creation - Features: Easy to assemble - Size: Each part has a different size, but standard domino size. Thank you for viewing! Note: Marbles are not included! You will need to purchase them separately! I bought these intending to build something, but I never used them. They are unused, but it seems someone played with the marbles, so they are not included. For those who enjoy crafting!
