To use this CREATTO kit, first, take out the flexible plastic tiles and the LED lights from the box. Refer to the illustrated manual to start building the pre - designed animals or decorations step by step. Or, if you're feeling creative, use your imagination to make your own custom 3D creations. Just connect the tiles together firmly and thread the LED lights through as needed. When you're done playing, keep the kit in a dry and cool place to prevent the plastic tiles from warping. Avoid pulling the LED lights too hard to prevent damage. Clean the tiles with a soft, dry cloth if they get dirty. Have fun creating!
