Insert Variety Pack: One of Each Type Plus Half-Track

One of each IMR insert type plus a half-track section so you can experiment with every customization option in the IMR system. Inserts are specialty pieces that drop into existing track sections to change marble behavior — adding pathway dividers, speed bumps, or design variations to tracks you've already built.

This variety pack is the easiest way to try every insert type before deciding which ones you want more of. Use them to customize race outcomes, add visual variety, or experiment with different track behaviors.

Compatible with IMR Circuit, Speedway, Grand Prix, and Jelle's M1 Hyper Loop. Made in the USA.
