Eco-Bricks Natural Wooden Bricks (45 Piece)

45 building bricks cut from FSC-certified wood: thirty 2x4s, eight 2x2s, five brick covers, and two axles with wooden wheels, plus ten colored pencils. The bricks click into LEGO and other plastic-brick sets, and kids can draw on the wood and erase it with a damp melamine sponge. Open-ended building works the same planning and fine motor control as any brick set, and the drawable faces add a design step of their own.

Basically a more sustainable version of LEGO made out of wood and bamboo for an eco-friendly alternative.
