Interlocking Three Pairs, designed by Stewart Coffin, made by Pelikan. This is listed in my notes as "Pelikan 19A", for whatever that means, and I'm not sure where that bit of info came from. The solution is interesting, though if you take it apart it will ruin it for you, so I recommend someone else disassemble it if you wish to give it a go. It has 6 pieces.There is a tiny stain on one end. Otherwise, the puzzle is very nice.

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.

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

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...
