Ultimate RD Shell

This is the cleanest cube solve you’ll ever perform.

Created by Takamiz Usui & Henry Harrius, the “Ultimate RD Shell” is the world’s first foldable, six-sided shell, made to be completely hidden until you’re ready to use it.

Here’s what you can do with it:

A cube is genuinely mixed by your participant and placed into a paper bag that was sitting completely flat on the table. They can look inside the bag to confirm it’s just their mixed-up cube. Then, under impossible conditions, the cube solves itself.

“Ultimate RD Shell” is:

• Ultra-thin and completely invisible
• Absolutely seamless
• Has a built-in locking mechanism
• Designed for real-world performance

But this isn’t just a one-trick solution. You’ll also learn the cleanest One Color Cube ever created (as seen on Penn and Teller’s Fool Us), and Henry’s Ultimate Do as I Do, a powerful and entertaining routine that plays huge for stage and parlor. The applications for this are nearly limitless.

“Ultimate RD Shell” raises the bar for cube magic, allowing you to perform under impossibly clean conditions that feel fair, open, and leave no possible explanation.
