Love JPerm? Now you can get a replica of his main speed cube, the YJ MGC 4x4 Magnetic, and support the at the same time!

Set up to JPerm's specifications, we use a combination of Martian, Lunar, and Stardust lubricant to dampen spring noise and maximize turning speed across all layers while focusing on maintaining controllable turning.

We contribute $5 to the JPerm channel for every cube sold.

Why does JPerm love this cube?

"This MGC 4x4 is such a satisfying cube to turn. It's fast but does not overshoot, and all the layers turn amazingly." -JPerm
