Marble Run Transparent Basic is a building kit that enables children to construct and then play with what they have made. The thrill of seeing the marbles rolling down the see-through chutes, inclined bridges and spinning the wheel is rewarding.
45 pieces including interlocking chutes, bridges, columns and spinning wheels. Children can build the models pictured on the box or experiment with other designs of their own.

For ages 4 - 12.
