Marble runs are an endless source of fascination for children (and many adults). Constructing them is even more fun. With this set of 45 unfinished hardwood blocks, you can build myriad runs, from simple designs to complex networks of organized troughs and vertical drops.
Well made in the USA, the set includes thirteen troughs with vertical drop holes (seven 6-1/2" long, six 4-7/8" long), ten double-sided troughs (two 4" long, two 3-1/4" long and six 1-5/8" long), twelve 1-5/8" long single-sided troughs, ten 1-5/8" square stand-offs with angled drop channels, and fourteen marbles. A storage bag with a drawstring closure is also supplied.
A well-designed, durable set to create stable structures. Great play value, for ages 3 and up.
