Lakeshore turn & learn magnetic gears. Used but in very good condition. Great stem tool. This incredible building set lets kids put together their own spectacular, spinning show! The interchangeable pieces slide together easily for no-fail designing. Children simply stick the gears onto a magnetic surface…fit them together any way they like…then turn one of the built-in handles to set the whole colorful creation in motion! Sturdy plastic set consists of 22 magnetic gears in 2 sizes. Large gears measure 3 3/4" Tags: Montessori, lovevery, guidecraft, lakeshore learning, learning resources, Melissa Doug, Hape, haba, plantoys, Janod
