Using Creatto is a breeze. First, take out the plastic tiles and start interlocking them. It doesn't matter if you're a beginner or an expert, the tiles fit together quickly and easily. To build the barnyard buddies, follow the general concept of how each animal looks and use the included pieces. When adding the LED lights, make sure to insert the 2 CR2032 batteries properly into the battery compartment. These creations are great for imaginative play. You can use them as props for your own stories and adventures. As for maintenance, keep the Creatto pieces away from sharp objects to avoid scratches. If they get dirty, you can simply wipe them with a damp cloth. Store the pieces in a dry place when not in use to keep them in good condition. Remember, these products are suitable for ages 8 and up, so make sure younger kids are supervised during play.
