How it's made. Four printed parts: the base, the lid (with the name inlaid flush), and a small hinge pin — lid and base carry interlocking knuckles along the back, the pin slides through, and the lid swings open past upright. The front latch is a flexible tab on the lid that clicks over a ridge on the base, like the original. A lip inside the rim keeps the closed box aligned and dust-tight. The school size holds full-length pencils, a ruler, and scissors; the compact size suits pens and markers.
