The previous-generation Master Kit shell, sold without a single tool in it: composite body, wheels, retractable handle, waterproof and dustproof. Lid pockets, SOS foam trays, and the hanging pallet are all here, so a pro inventory built piece by piece gets the same organization the factory-filled kit ships with.

The Master Tool Kit Case (970MASTERKIT) is the heavy-duty composite case that ships under the previous-generation Master Tool Kit, sold separately for mechanics who already own a tool inventory and want to consolidate into a kit-grade storage system. Pre-2.0 generation case; same composite construction, same wheels-and-retractable-handle build, no 2.0 layout refinements.
The case is the same heavy-duty composite that ships under the previous-generation Master Tool Kit. Designed in conjunction with professional users; sized to roll into a paddock or a workshop and open into a working bench.
What the case carries
A thoughtful pocket-and-SOS-foam-tray layout sized to a full pro tool inventory. The case is built for practical and secure organisation: pockets accept the tools that need to stay at hand, SOS foam trays accept the larger workshop tools that need their own footprint, and the case still leaves room for brand-specific additions a particular workshop runs.

Built in Zreče, Slovenia
Unior has been forging hand tools in Zreče, Slovenia, since 1919, and is the official technical partner of multiple World Tour and downhill teams. The Master Tool Kit Case is the storage half of the kit that travels with team mechanics on the road; sold separately for mechanics who want the case without the configured tool set.
Pro tip from our mechanics
If the workshop standardizes on the current-generation 2.0 kits, the Master Kit Tool Case 2.0 is the matching newer case with an updated pocket layout and IP67 rating. The 970MASTERKIT (this case) is the right answer when the workshop has been running on the previous-generation Master Kit format and the case has finally given out.

From the press
The big new Master Kit case gets a foldable handle opposite the hinges. It also now adds durable sealed bearing wheels to get you through the airport (& pits) faster and a telescoping handle that slides out of the base.
