Lock Box, by Eric Fuller [2020 Edition]

Tricky and twisty, one of the greatest solving journeys I have had the pleasure of experiencing. Still functions perfectly.

This copy's main box is made from a beautiful figured quartersawn sapele, and the key is made from sapele and jatoba. (The key comes in a small black satin bag with a drawstring.)

Upon solving the puzzle, you will find a prize, and Eric Fuller's small 'e' signature, as well as the date of production: "6/20" [June 2020]

It was released on 7/31/2020 - there were 133 copies made of the 2020 edition.

It is no longer available.

From the original 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.

This puzzle is very precise and must be kept between 40 and 60 percent humidity at all times. Do not expose it to high humidity conditions under any circumstance. We do not guarantee proper operation if stored outside these conditions."
