Large Format Magnetic Marble Run 158pc Pastel STEM Set KBLG158

Build. Test. Watch gravity take over.

Go bigger with a more substantial marble-run build.

The KBLG-158 combines large-format pastel magnetic tiles with translucent tracks, curves, funnels and marble-run components. The larger pieces create bigger structures more quickly and provide a substantial hands-on building experience.

Build towers and multi-level pathways, release the balls, then change the route and try again. The 75mm square tiles are approximately twice the width of Kebo’s compact-format squares, making the difference in scale immediately noticeable.

Children explore gravity, motion, direction and cause-and-effect while developing spatial reasoning, creativity and early engineering thinking. Age 3+
