This is one of my favorite puzzles and one of the best work from Eric Fuller.
This simple looking cuboid with a key has many secrets to unlock and it will take you good amount of time to solve it!
This copy is from the second release with better construction and a hybrid metal key improving longevity of the puzzle! The walnut on my copy has a nice shimmer to it which I've tried to showcase, but is something to be observed in person only. I am the first owner of this puzzle.
Puzzle was kept in a humidity controlled chamber with humidity between 48-55%. I've solved it once after receiving and once again today to test the solution. Aesthetically, the puzzle is in pristine condition.
Description from the product listing:
Lock Box is a sequential discovery puzzle box. Its simple appearance
hides a very complex mechanical mechanism that requires multiple
discoveries to open. No gravity moves, spinning, tapping, banging or
force is necessary or allowed.
I think this is one of my best designs to date. Multiple steps and
discoveries are required, with knowledge of the mechanism coming in
stages until the box finally opens to reveal its prize.
We sourced a very rare plank of Claro Walnut for this edition of Lock
Box. Claro walnut trees are a blend of species, created by grafting an
English walnut to either black walnut or a California walnut. Claro is a
Spanish word meaning clear or bright, and this is used to identify the
wood cut from the bole of walnut orchard trees.
This is also our first puzzle that incorporates precision-milled
metal components combined with fine woodworking. The shining aluminum
key shaft really stands out against the intricate visual texture of the
wood.
Can combine with other puzzles if you win more than one. Will be shipped via FedEx and insured. Payment preferred via Wise, but will accept PayPal as well.
