The GAN 354 M V2 is an update to the original 345 M, featuring frosted plastic and a new Numerical IPG core with hand-adjustable GES nuts.
Being slightly smaller at 54mm, this cube is great for those with smaller hands, and for one-handed solving.
The Standard version comes with only the pre-installed purple GES nuts, whereas the Explorer version also comes with extra sets of yellow, green, and blue GES nuts for further adjustability.
