+Burr (Plus Burr) is a six-piece burr in an unconventional shape designed by Stephan Baumegger in 2015. The name derives from the negative space on each assembled face which resembles the addition symbol. With a level 8.1.2 disassembly is not trivial, but not overly challenging. I recommend disassembling and scrambling the pieces for a great assembly puzzle.
We have made two variants for this release, one with light white oak and rich walnut, and another with bright ash and intricate zebrawood. The wood pairings give each puzzle a visually pleasing contrast, with the large, chamfered pieces being easy to handle and providing very smooth movements.

These puzzles are listed as part of the Reserve Puzzle Program: for each newly released puzzle on Cubicdissection, four copies are reserved. After that puzzle is sold out, they are listed one at a time in the next four Marketplace events with a one penny opening bid and no reserve. This is done to discourage profiteering and flipping by making more than one copy available as a competing identical listing.
