Love JPerm? Now you can get a replica of his main speed cube, the YJ MGC 7x7 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?
"The MGC 7x7 turns as fast and effortlessly as the 6x6, which makes solving it so much more fun!" -JPerm
