Using these Magicube crystals is a breeze. You can start by simply picking up two cubes and attaching them from any side. Then, keep adding more cubes to build amazing 3D structures and new shapes. Whether you're building a small tower or a big complex model, just let your imagination guide you. Since these cubes are magnetic, they'll easily stick together. Even if you have some motor problems, you can still assemble them without much trouble. When it comes to safety, make sure to keep these cubes away from very young kids who might put them in their mouths. As for maintenance, you can clean them with a damp cloth if they get dirty. Don't expose them to strong magnetic fields other than their own, as it might affect their magnetism. And store them in a dry place when you're not using them to keep them in good condition.
