THE ORIGINAL Play Clips, invented many, many years ago by Bill Bluhm, owner of Heartwood Arts! Over the years, it undisputedly has become one of the most popular item in any Waldorf school or home! Unfortunately also copied and sold by many, but here the ones from the originator himself! An essential tool for every serious builder of forts, houses, caves and dwellings. Perfect fit for little hands (and big ones!). Carved from pine wood which is easy on small hands, from locally sourced wood.
