Using the Creatto building set is a breeze. First, take out the plastic tiles and start interlocking them. Since they're easy to connect, even beginners can handle it. For building the animals like the bald eagle, grizzly bear, bison, or skunk, follow your creativity or look for inspiration online. To light up your creations, connect the 100 - LED light string to a USB power source (you'll need your own USB power adapter). When it comes to safety, make sure kids don't put the small pieces in their mouths. And to keep the set in good condition, store the tiles and lights in a box or container when not in use. Avoid exposing the plastic tiles to extreme heat or sharp objects that could damage them.
