Each Moyu RS Pyraminx M comes with a small accessory box, containing a screwdriver, instruction manual and tools for adjusting the springs. You make these settings by first lifting the colored caps that sit on the corners of the Pyraminx. To change the feel of the cube, it is recommended to first tighten the screws sufficiently hard, so that it cuts corners well. Then you can use the included tool to turn the blue ring that surrounds the screw. By screwing the same number of clicks under all corners of the Pyraminx, you can adjust the spring’s length and thereby strength. This way you can change how loose or tight the Pyraminx feels without having to risk it popping.
Moyu RS Pyraminx M also comes in a Maglev version, more information is available on the product page for the Moyu RS Pyraminx M Maglev.
