Crenal, designed by Gregory Benedetti and made by Fuller. This is a unique 6-piece burr with diagonal intersections and unusual piece play. As Eric described it in the original listing (2016), "The peculiar back and forth gate movements are extraordinary." They are. The puzzle was "a little loose to account for dry conditions" when made, and it's still a little loose, but functions well. See link above to original listing.

Rombol version of this well known caged burr which I found surprisingly tricky, even with only three pieces including the cage itself. Moves smoothly.I accept PayPal. Buyer can expect to pay $13 shipping domestic within the US and approximately $35 internationally. Happy to combine shipping on multiple items.

This is a solid packing puzzle from a lesser-known creator, Steve Smith of Burnt Oak Studios. Voxel size is a hefty 2cm; this could be a great beginner puzzle for someone any age who is new to the world of interlocking/packing puzzles. I accept PayPal. Buyer can expect to pay $13 shipping domestic within the US and approximately $35 internationally. Happy to combine shipping on multiple items.

Great puzzle by Terry Smart, 25 moves to release the first stick!  Contrary to Eric's description at  https://cubicdissection.com/collections/discontinued-work/products/copy-of-sextbordthis will be shipped assembled because it is safer and easier to pack.  It's an entertaining disassembly too!

Stephane is well known for high level burr puzzles.  This is no exception but it is doable (if I can you can, believe me).  Reassembly, however, was something else!  Read Eric's description at  https://cubicdissection.com/collections/discontinued-work/products/prison-burr

One of my fav burrs ever. Eric said this about the ones he produced (this one is made by Alfons).With a unique level 20.3.1.4 solution it's not for the faint of heart. Solvers are reqarded by a pleasing geometric sculpture that validates your puzzle credentials big time!

Stewart Coffin design Fancy This! #115-A made from mahogany.Seven pieces form the classic cluster shape, but instead assemble with both coordination motion and serial interlocking. IPP17 Exchange puzzle from Nick Baxter. Includes original box. The puzzle is in excellent condition, pieces go together tight and smoothly, a few small gaps in places once solved but displays very nicely.

From Pluedro:"Despite its decent and honest appearance, this puzzle requires 25 moves to remove the first piece from the assembled shape.While Juno had been playing with the idea of Grooved 6 Board Burr #1, he thought that there could be several variant grooved board burr puzzles dependent on where he put pins and grooves on the puzzle pieces. It was the reason why he put #1 to the first grooved 6 board burr. We might produce #3, #4 and so on if he finds an interesting idea for the series.Unlik...

Crystal Lattice 1, designed by Osanori Yamamoto, made by Pelikan. Comes with assembly instructions from Pelikan. Shipping weight with packaging is 8 ounces.

Icosahedron/Dodecahedron - design and made by Wayne Daniel. The fit isn't as accurate as it was when new; some small gaps opening up between pieces (see photo). This comes with a DVD called "One Hundred Seventy-Eight Cuts And Some Glue". I just now tried it in my DVD player; it works great.Shipping weight with packaging is 12 ounces. 

Chiasma - design by Yavuz Demirhan, made by Pelikan. Shipping weight with packaging is 12 ounces. 

Galaxy Z, designed by Osanori Yamamoto, made by Pelikan. Shipping weight 1 lb 1 oz with packaging.

From CubicDissection:"Secret Burr is a re-release of a puzzle I made very limited copies of in 2002. Unique in that it's difficult in both assembly and disassembly, there are two locks inside the burr that interact much like Cutler's Ball Bearing Burr. Instead of steel bearings, Secret Burr uses small wood rectangles. Precision crafted of fine hardwoods, this puzzle not only looks exotic, but has the trickiness to back up its appearance."https://www.puzzlemad.co.uk/2020/01/theres-right-way-and-w...

Combination Lock STC128, Stewart Coffin - made by Mark McCallum, purchased 2009.This is a very tricky coordinate motion puzzle; finding the right way to get it apart is not easy. Six pieces. It took me about 1/2 hour just to find out how the thing came apart. The movement is smooth, but it's difficult to figure out the best place to push or pull. Shipping weight 12 oz with packaging.
