Love JPerm? Now you can get a replica of his main speed cube, the YJ MGC 5x5 Magnetic, and support the JPerm YouTube Channel 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?
"Effortless turning is the most important quality of a big cube that is set up well. The MGC is the fastest 5x5, yet remains incredibly stable to turn." -JPerm
