Can a pyramid puzzle actually feel weightless while maintaining surgical precision? The GAN Pyraminx 60 Magnets proves it is possible by weighing in at a mere 64 grams, making it the lightest option currently on the market. What sets this apart is the sophisticated magnetic core-positioning system, which uses 60 magnets distributed across the corners, edges, and core to ensure incredibly smooth, low-resistance turns. You can easily customize your tactile experience using the GES+ elastic system, allowing you to twist and adjust tension via the tuning nuts. With 120-degree corner cutting and a scratch-proof honeycomb surface, this puzzle is engineered for high-speed solving without sacrificing stability or control.
