The "nuts and bolts" appearance may lull you into believing this to be a straightforward puzzle, but it is a total brain drain. Inventor Oskar van Deventer presents two challenges: 1) remove the small nuts by disassembling the nutcase, and 2) change the order of the wording on the bolts from "nut-case" to "case-nut."
