Two obviously related designs by Greg Benedetti.  Only two pieces in each but 1 needs 8 moves and 2 needs 7!  Be careful as, to the best of my knowledge, the pieces are not interchangeable!

Another brilliant packing puzzle by the designer of the award winning "Casino" puzzle, Harun is a tricky assembly. Six notched sticks and six small planks pack into the box two different ways. The solution is trickier than is apparent given the simple pieces.Construction of this puzzle is excellent, with a precise fit which displaces a cushion of air when the entire assembly is dropped in at once.For multiple items, combined shipping is available.

Beautiful sequential discovery puzzle box, finely crafted by Dee Dixon.  In like new condition.   Pairing down my collection; hate to see this go.  Eric writes this about the puzzle:Where's My Hammer is Dee Dixon's first release on Cubicdissection. This sequential discovery box is incredibly well made and packs a ton of punch. The box into a very unique and well-crafted; while Dee may be new to puzzles, he's clearly spent a lot of time in the woodshop before discovering his talent for puzzl...

Fidget burr was an easy decision to make. A seemingly simple 3x3 cube, it's actually a five-piece interlocking burr with a level 12 solution. Three burr pieces nest inside two identical frame pieces. Disassembly of this puzzle is VERY tricky, with many false paths and dead ends.  Fidget Burr is a ton of fun and it turned out very well.This puzzle is shipped assembled. For multiple items, combined shipping is available.

Pack the Puzzle Squashed from Naoyuki Iwase (Osho)Goal is to pack the six pieces into the box with the restricted T-shaped opening.  The pieces are composed of "squashed" voxels, which I found moderately challenging.  There are multiple assemblies, but I found only one that enabled the pieces to be packed into the box.Puzzle has been stored in its original bag with instructions after being solved.  I just tried it out again and it still took 30 minutes to solve.  But everything looks and fun...

Pairing down my collection. Never got around to attempting this one, unfortunately.  Brian Young makes some of the best SD puzzles out there. Ages is named after how long it took the puzzle to be made from original conception.  From Mr. Puzzle’s site:This is not a binary burr even if it seems to have some of the elements. All the moves are random. That makes it less predictable to solve. And the burr has no frame; even the Coming of Age MkII pieces are technically making a frame which is ho...

Leontev's 205 Minutes is a masterpiece in both design and construction. So named because if you make one correct move per second, non stop, it will take you 205 minutes to disassemble. This n-ary juggernaut requires over 12 thousand moves to disassemble. Once disassembled, a reset mechanism allows you to quickly bring it to the original state with only four moves. It also comes with the 136 minute piece which only requires around 8,000 moves to solve.It was a difficult decision to make this puzz...

"Nope Box" is a very fun little puzzle box with sequential discovery style elements.

A 5-piece design by Jos Bergmans in the TIC category, level 1.5.4.4.  Ka'apuni means to go around or turn in the Hawaiian language.  Beautiful woods well crafted by Brian Menold.

from cubicdissection.com:Board Burr Rack looks quite simple. Simply slide four burrs into the rack spaces created by the frame. Easy, right? Unfortunately the two cubes trapped inside the rack makes that task substantially more difficult. Each board move affects its neighbors due to the two unit size of the cube it's interacting with, creating a shifting maze of confusion. When fully assembled, none of the boards are able to be completely removed without manipulating the cubes inside. Lots of fu...
