Cruiser 4 Piece Puzzle

Perhaps the most fun you can have with 4 pcs of wood…
A brilliant Stewart Coffin design that combines elegance and apparent simplicity into something that is actually cunningly diabolical. Despite only being 4 pieces, few will get this one quickly. The goal is to get all 4 pcs into the rectangular opening in the base.
It’s a great one to leave out on a desk or coffee table as it does not look intimidating, and people will want to try it. The puzzle comes unsolved, however a written solution is included.
Made from ¼” thick hardwoods; each piece from a different wood. Precision laser cut with a smooth lacquer coating.
Dimensions: 5.5” x 3.3” x .6”
