This is the 2018 version of 4L with the plexiglass bottom. The new one is a solid bottom. I'd argue that the plexiglass bottom adds something to the solve. I have to be vague but I do consider it a more satisfying puzzling experience and solve with the plexiglass bottom. 3% PayPal fee will be applied to final price. 

From Cubic Dissection release notes: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.

6% paypal fee is paid by the buyerShipping is calculated after auction is closed.Strap is (in my mind) an interesting successor to Alkema's Clamp puzzle. The two pieces are filled by four cubes which can manuever internally. The solution is tricky and non-intuitive...all pieces are accessable so there is no need for gravity shifting. There is a rotation shortcut which is quite apparent with disassembly but not at all apparent during assembly, which is nice in my book...almost like two different ...

6% paypal fee is paid by the buyerShipping is calculated after auction is closed.Rift is such a simple design it's elegant. Three burr pieces and a two piece cage that dances around the assembly. The moves are so unconventional that the level 8 solution is tougher than you would expect. Disassembly has a trick to it as well. This is an excellent puzzle, I'm glad I made it, and I'm looking forward to its big brother "Schism" in the next update.Construction of this puzzle is excellent. Fit is dead...
