Using this Chameleon Kidz creativity kit is super easy! First, to mix colors, connect two Blendy Pens to the Fusion Chamber and then twist them. You'll get amazing custom color blends right away. If you want to use the airbrush feature, attach the airbrush tool to a Blendy Pen and start creating. For safety, make sure kids don't put the markers or airbrush parts in their mouths. When not in use, keep the markers capped to prevent them from drying out. Store the kit in a cool and dry place to maintain the quality of the markers and other parts. Have fun creating!
