The Pocket Box is a compact, fidget-friendly puzzle that’s ideal for introducing friends to puzzle boxes. Sized like a deck of cards and weighing 150 grams, it’s easy to carry around. The puzzle is engaging, with a solve time of about an hour for beginners and 15 minutes to an hour for experienced puzzlers. Made from 3D-printed black PLA and silver and gold silk filament highlights, it measures 90 x 68 x 24 mm and feels solid. The final compartment is large enough to hold a rolled-up bill.
