The Haselgrove box is a unique puzzle based on
the locking mechanisms of the Egyptian pyramids!
While this puzzle
is not too difficult, it is a lot of fun, and very clever.

The instruction sheet accompanying the puzzle says this:
“Jeniver Haselgrove designed this Trick-Opening Box which can
be opened or closed by a mysterious mechanism. Already the old Egyptians had knowledge
about this mechanism and they used it closing the pyramids. Moveable pieces block inside
the centre part with the initials of the designer (H + J) after correct moving or they
give it free.”
“A mechanical puzzle is a self-contained object, composed
of one or more parts, which involves a problem for one person to solve by manipulation
using logic, reasoning, insight, luck, and/or dexterity.” - Jerry Slocum
