Penultimate Burr Box Set Puzzle Box

For sale is a limited edition The Penultimate Burr Set by Eric Fuller.
This set of 27 numbered pieces combines to make hundreds of puzzles, from fairly simple solid assemblies to extremely difficult higher level assemblies.

The box itself is quite special; the lid lifts off to reveal precise, ordered rows of burr sticks. What's missing are the instructions, hidden in a concealed compartment and protected by a puzzle box mechanism. You must solve the puzzle box before beginning work on the burr sets. This puzzle offers hundreds of hours of puzzling value!

The burrs are accurate and uniform; the box lid fits with precision, displacing air as you open or close it. The puzzle mechanism is deviously hidden and cleverly concealed. Once discovered, it's easily repeatable.
