Magnetic 54mm speedcube from Gan.
The GAN354 M V2 is a stickerless speedcube from GAN. The main difference between this and the good ol' V1 is that this version includes frosted plastic, an upgraded core & the GAN GES elasticity system, which combine to improve feel, control and speed.
This slightly smaller 54mm speed cube will suit those with smaller hands, and has become a favourite for one handed solves. Tensions are easy to change; simply push the spring down and turn to preset tensions.
