Ideal for creating a castle setting—complete with watchtowers, crenelated brick walls, and a stone arch—the 16 blocks in this set for youngsters 3 and up can become any number of things; make the tower tops into fancy chairs, flip the walls over to become train cars, or stack the square pieces into a tall flight of stairs. (And the set is so affordable, you can buy two, for twice the possibilities.) Made from both painted and unpainted pieces in solid, environmentally friendly rubberwood, the set also features molded specialty pieces of composite rubberwood, and includes a horse and two knights. The pieces measure from 1¼ to 2¾ inches long.
