Using the CREATTO kit is super easy. First, take out the interlocking plastic tiles and the LED lights from the box. Look at the illustrated manual for some design ideas, or come up with your own. Start connecting the plastic tiles according to your plan, and then add the LED lights to make it illuminated. When handling the tiles, be careful not to bend them too hard as they might break. After use, store the tiles and lights in a dry place to prevent damage. If the LED lights stop working, check the battery or connection. Enjoy building your own 3D masterpieces!
