The interior is divided into six separate compartments, giving pinion gears, screws, nuts, ball bearings and other small essentials their own space instead of mixing loose in a toolbox.
Tamiya lists this case as fitting the same broad chassis range as most of the Grade-Up Parts line — Type 3 through Type 5, Zero, FM, FM-A, Super-1, Super-II, Super FM, Super TZ, Super X, Super XX, Super TZ-X, VS, MS, AR and MA chassis — reflecting that it's general storage rather than a car-specific part. Tamiya also markets it alongside a set of related storage products aimed at the same trackside kit: the Mini 4WD PRO Racer's Box (Item 15354), Mini 4WD Portable Pit (Item 15424), Mini 4WD Motor Case 2 (Item 15505) and Mini 4WD Battery Case 2 (Item 15521), each covering a different category of gear a racer carries to an event.

Every Mini 4WD parts group explained: chassis, motor, gears, wheels, rollers, stays and dampers. What each one changes, and which to touch first.
Knowing when to replace Mini 4WD parts saves a race. Wear signs on gears, bearings, rollers, shafts and braces, and what to carry as spares.
