This set is has five less pieces than our TB36, all the same educational fun for a bit less.
Tree Blocks (31 piece)
This is our 31 piece set of TreeBlocks. Made in Wisconsin by the Amish with the bark securely intact. They are unit blocks, precisely cut into 2cm increments for mathematical soundness in building. They´re based on the metric system because increments of 10 are intuitive and used by the majority of the world.
