Welcome to Nextcube, home of the world record-breaking speedcube! Nexcube is ergonomically designed with a unique mechanism for smooth turns. To solve the puzzle, twist and turn your Nexcube, manipulating the cube until both sides are a single solid color. Sensory Play Nexcube makes a great fidget toy to release restless energy. Fidget toys are self-regulation tools that will help with focus, calming, and active listening (and they're so much fun!) Anti-Pop Design The new anti-pop design ensures the cubes don't fall out of the cube during use. Large Hole Design Thanks to the round holes in the corners and edges, NexCube moves extremely smoothly. Adjustable Elasticity Adjust the Speedcube NexCube elasticity to your personal preference. Screws and springs in the middle of the cube make it possible to adjust this. To adjust the flexibility of the cube, you can remove the top of the middle block and adjust the screw with a small screwdriver. Stable Structure Professional structure inside the cube improves the overall performance of the cube. This makes the Speedcube NexCube not only faster but also more stable. A Cube Without Stickers The Speedcube NexCube does not include stickers. So there is no way to solve the cube by changing stickers. Additionally, the cube has a good grip without these stickers.
