This is a set of building blocks from Oak Village, made from various tree species with different weights, colors, and textures, and comes with a carrying bag. I purchased it about 10 years ago and used it a few times, but it has been stored at home for a long time since then. Each building block is branded with the name of the wood. To prevent them from getting lost after playing, an original Oak Village cloth bag is included. This helps children develop the habit of putting things away after playing.
