Create your own stellar LED light with this cool kit! No glue needed - simply peel off the clear cover to reveal the adhesive. Next, pick up a colorful, transparent gem with the included stylus and place it on the adhesive. Once your design is finished, wrap it around the plastic jar and attach the jar to the lid, which features an LED light. Turn on the power and cast radiating light patterns on the ceiling with one of the two included shadow disks. This craft is easy and fun, while helping children develop fine motor skills. Assembled light measures 6-1/2 x 3-1/2" and is powered by a USB cord with integrated on/off switch. (USB power adaptor not included.) For ages 6 and up.
