Key Features & Design
- Divided Compartments: Usually includes 36/37 divided slots to neatly sort letters (e.g., L and R for Left and Right) and individual numbers without them getting mixed up.
- Sloped/Grooved Trays: Many professional cases (like those used in NDT) feature sloped, ridged edges in each compartment so you can slide and pick out the small lead letters smoothly.
- Material: They are typically constructed from high-density plastic, molded polycarbonate.
