The Gan 356 Air aims to achieve a lighter, faster and stronger speed cube.Many subtle but important design changes have also been made in the Gans 356 Air, which allow it to be even more stable and lightweight than any of its predecessors. Gans has created a patented, color-coded spring elasticity system called the GES (Gans Elasticity System).Gan 356 Air is the first high-end 3 by 3 speed cube that rejects metal gasket,the metal gasket is the part with worst accuracy in a cube,it defects solving experience. This is the Master version of the Gan 356 Air. The Master version features the Gan half bright sticker set pre-applied to the cube. It also comes with the Adjusting Tool and a set of Red (S6), Orange (S7), and Yellow (S9) GES Components. Please note that GAN is transitioning from the Red, Orange, and Yellow GES Components to the Green, Blue, and Purple GES Components, so some packages will come with the new GES Components instead.
