Bring a touch of kinetic art to your workspace with the "Ultimate Desktop Diversion." This sleek, matte-black marble run is designed for "grown-ups" to experiment with momentum, friction, and gravity while taking a break from the daily grind.

​Product Features:

​Complete Building Set: Includes all 22 black structural pieces (ramps and connector blocks).

​Modular Design: Build various configurations to keep the run challenging and fun.

​High-Quality Materials: Solid feel with a professional aesthetic, fitting for any office desk or study.

​Original Tin: Comes in the original collectible metal storage tin.

​Note on Contents:

​Please note that this set originally included 8 steel ball bearings. This listing includes 7 ball bearings (1 is missing). This does not affect the buildability or the fun of the run, as you typically only roll one or two at a time!
