from cubicdissection.com:The Loopy Burr came from the genius brain of Junichi; a very unusual six piece interlocking puzzle with pieces that form three intermingled loops once in the proper position. Finding that position takes eleven moves, and is downright tricky due to the space caused by the loops. Good luck!Construction of this puzzle is outstanding, with our usual precision down to several thousandths of an inch.

The difficulty in making it, getting the tolerances right to achieve the slides with no slop. The brilliance of the design. But I won't...I'll just say this:Slant is hands down the best cube puzzle I've ever seen.Construction of this puzzle is perfect. Every piece fits with just the right tolerance. It's a delight to solve.38 copies made...
