The "Master" is the big brother of the popular "Pro." This tool case was developed and tested with the support of professional mechanics and is designed for true professionals. A thoughtful layout with particularly sturdy tool holders and SOS foam inserts ensures that all tools are conveniently and securely in place. All holders in the foam inserts are designed for Unior tools. Additional holders and modular inserts in the case bottom accommodate tools according to your own needs. The case features a retractable handle and is equipped with wheels, making it perfect for air travel. The "Master" tool set includes 94 carefully selected tools for every need, whether for fixed or mobile workshops, team support, or demanding DIY projects. The tool case is specifically designed for bicycle tools. It is made of extremely durable plastic and is dust and waterproof. Flaps in the lid can be securely closed with Velcro to safely hold tools in place when closed. The flaps and lid are lined with 44 tool pockets on the inside. The largest of these can hold Unior T-handles up to size 10. Specially shaped pockets are available for L-handles up to size 1.5 mm or other smaller tools. There are also two side trays measuring 280 mm × 250 mm with foam inserts and holders for tools. When not in use, these trays are stored inside the case itself. When working, the trays can be attached to the outside edge of the case, ensuring that all tools are readily accessible at any time. The side trays have metal bottoms, making them particularly stable and sturdy. At the bottom of the case, there are additional trays measuring 385 mm × 280 mm with SOS foam inserts. Small part organizers with three compartments each and enough dividers to create up to 21 compartments. Additional space for spare parts and lubricants.
