Wood blocks are a great toy for all kids. They will get used! Traditional Lincoln Logs are fun and already pretty eco-friendly, but these bamboo builders are even more so. Made of organic bamboo, a very sustainable material, there are no plastic pieces. Even the container is not plastic, unlike a traditional Lincoln Logs tub. (I'm not sure of the material, but it appears to be a paper product, similar to a poster tube.) Note that this toy has small pieces, so it is not for kids under 3.
