From cubicdissection.com:Six Slabs is a unique packing puzzle reminiscent of the Hexahedroom design. Six uniform "slabs" must be packed into the box, which has three openings in a non-symmetrical pattern. This is complicated by two fixed blocks inside the box. With a level 1.1.9.3.2.3 solution, Six Slabs is non-trivial to solve.Crafted from Curly Maple (box) and Wenge (pieces). Great care was taken during construction, with Wenge accents on the box corners and extremely precise dimensions. Ext...

The artisan half hour puzzle cube (STC-29) by Stewart Coffin. Produced by Eric Fuller at Cubicdissection. This is a pretty straight forward puzzle. The goal is to build a cube. And of corse it was originally named 1/2 hour cube because that’s how long it would take the average person to solve it. Furthermore I will mention that this puzzle doesn’t come with any box or documentation but I did email Eric fuller before listing and I confirmed that it’s and authentic CD half hour cube.

From twobrassmonkeys.com:Thirteen notched bars slide and interlock to create a pleasing four pound mass of interwoven solid brass.   The puzzle comes disassembled in an aluminium presentation case.  Although the puzzle looks and feels intimidating, we carefully selected the design so that it can be assembled by the determined puzzler. 

This is my copy of Alken. It's in great condition."Alken is a puzzle box with (mostly) trinary movement, This basically means each piece needs to move three steps before the next piece can be moved. With each additional piece moved, the count grows considerably. This movement is similar to the Aquarius Puzzle. There are two possible configurations based on how the lid is inserted. One set up requires 75 moves to open, the second configuration creates a grueling 261 move challenge."This Puzzle ...

A beautiful little 6-piece board burr needing 34 moves to free the first piece (no rotations).  Can be sent assembled or not, as you wish.

Item is in original condition. However, near one of the joints where a dowel was placed in for reinforcement there is some slight damage that is noticeable (see last photo).  This is the condition I received it in when purchased brand new & is purely cosmetic. This has been kept in a humidity controlled room at 50% RH. The puzzle solves as intended & the fit is perfect.  **Buyer to pay shipping cost, please wait until final updated invoice before submitting payment.Description from Wood Wonder...

This is my copy of Spiral. It's in perfect condition.This description was provided by Cubic Dissection who produced this puzzle."Ok, this is the wicked difficult contender in this month's update. It has a unique level 14 solution with a TON of false moves and dead ends. Honestly I could barely get this little sucker apart without the solution, much less back together. As the name implies, the four ring pieces spiral around the central column of stick burr pieces. Very attractive, VERY difficult...

If you haven't heard of Where's My Hammer, then you are brand-new to the puzzling world (in which case, welcome!) or you've been living under a rock! (understandable considering covid)It's the best puzzle Dee has ever made, and he's yet to top himself so far! It even reached the top 10 in the IPP 2020 last year, so you know it's not me being biased. It's called the way it is, because Dee's son was a tester and snapped yelling for a hammer when he struggled to open this puzzle. It's not easy in t...
