Item is new condition and includes original packaging.Description from Cubicdissection Website by Eric Fuller:Stumbling Blocks is a brilliant puzzle that I've been wanting to make for a while. When Pit mentioned that he had a more difficult version I jumped at the chance to make it. Packing the four pieces into the frame is the goal, and the way to get there is amazing. I can't tell much about this puzzle without giving things away, but I'll say that it has one of the best "Ah-ha!" moments I've ...

Well named as the pieces do seem to want to fidget, especially during re-assembly.  Read Eric's description at https://cubicdissection.com/collections/discontinued-work/products/fidget-burr

This puzzle has not been opened! Still in shrink wrap. From woodwonders.com:The RIPs are here! My second offering from Andrew Crowell's RIP designs is RIPtide. I chose this one because of the rather unique rotations that it has. Although there are several, one will have you scratching your head and give you a nice "AHA"  and not at the completion of the puzzle. But now I have given too much away, or have I? I don't think you will be disappointed with these puzzles. Reinforcing with birch dowel...

From woodwonders.com:Rotothorpe #1 is a really cool design in my opinion. I have always loved this type of puzzles. I know many people do not but this has been designed by Andrew Crowell so you know there will be a rotation or twist or something to confound you! Since this puzzle ships with a piece left out of the assembly the total moves of 17 is not applicable to your predicament. The Walnut version is made the same way as the padauk and purpleheart versions but with wooden dowels and not bras...

This puzzle is unopened and still in the shrink wrap!From woodwonders.com:The RIPs are here! Board Burrs have always been a favorite of mine and these are now at the top of my list of favorite Board Burrs. Assembling these is sure to test you. The rotations needed to assemble these are really a cool addition to the design. I remember making Frans de Vreugd's Tricoloure a few years ago and the unique move of swapping positions of two of the pieces was a great twist. These RIP designs take that to...

Despite their similarity, the pieces interact uniquely to assemble into the traditional board burr shape. With a level 8.2 solution, this puzzle is approachable yet fun for all experience levels.************************************************************These puzzles are extras and oddballs that have accumulated in ...

This is a really nice construction of this classic puzzle. I’ve solved it just a couple times. And for most of this puzzles life, it has been been stored away in airtight containers.
