This is a higher order puzzle based off of RCP's previous design, The Trapezoid Edge puzzle. This version changes the 3x3 mechanism out with a non-proportional 3x3x5 mechanism. This is without a doubt, the hardest (to solve) puzzle RCP has made to date. The original arm core was replaced with a ball core. This Trapezoid Edge SX turns very nicely, even on the thin slices and is very stable. The puzzle comes fully assembled and stickered.
