• Form factor: compact, tabletop size suitable for display or handling

How to use

Begin by examining the overall assembly to identify movable joints and contact points between the metal components. Use steady, controlled pressure and small rotational motions to test how pieces slide or pivot without forcing parts apart. Work methodically, keeping track of the sequence of moves needed to separate components so they can be reassembled. If pieces feel jammed, reverse recent motions and try alternate angles rather than applying excessive force.

Usage recommendations

Store the puzzle in a dry environment to prevent corrosion and avoid dropping it onto hard surfaces to preserve alignment of the metal parts. When cleaning, wipe with a soft, dry cloth; avoid harsh chemicals that could affect surface finish. Allow time between solves to review the mechanism and plan moves carefully to extend the service life of the puzzle.
