These are wooden bricks, red and black, about 1 inch in diameter. They are only "stackable" in the sense that you can place one slice on top of the other. In practice, they cannot be stacked as there is no mechanism to lock or prevent the top from slipping off. There are concentric rings on the top of the piece that probably needed to be pressed in to allow the small disc below to hold the two pieces in place, but that wasn't enough for the pieces sent to me. Most likely an error in the stamping process. While you can still mean "king" by flipping a stone, my grandkids love the stacking method, which is problematic with this product.
