This brilliant puzzle by Mineyuki Uyematsu (MINE) from way back in 2006 is enormous and, aside from its puzzle value, it looks gorgeous as a sculptural work on a shelf.  Produced by Bernard Schweitzer (with his sticker still on it).  When taken apart it's  hard to figure out how its three 4x4x4 cubes go back together.  Solved once and sitting in storage since then, so I'm selling it so others can enjoy this fantastic puzzle.

This classic by Osanori Yamamoto, Top, is a challenging disassembly puzzle, and when solved it’s an even harder assembly puzzle.  It has just 4 relatively simple pieces yet has a surprisingly complex solution - requiring rotation.  The pieces slide extremely smoothly, so smoothly that there are two small magnets to keep the pieces in place. Made by Pelikan Dec 2017.  Solved only once, selling so that someone else can enjoy this rare delight.

Item is in brand new condition.Pack four pieces into box so that when lid is inserted all pieces are positioned below lid surface (not protruding out of hole in lid). A seemingly simple puzzle but very unorthodox solution for an unrestricted packing puzzle.

A very interesting design, it combines a simple packing puzzle with a very unconventional box.

With many assemblies outside the box but only one inside the box, this is a fun solve for sure!...
