The UFO stretchy flyer is an incredibly stretchy, floppy, soft flying disc. The center contains squeeze-to-activate multiple LEDs that light up and flash for playing in the dark. One squeeze turns on a multi-color LED module that cycles through several flashing patterns for 10 seconds, then automatically turns off. Squeeze again to turn on. This approx. 5" diameter disc (unstretched) flies over 100 feet, and the center ball provides just the right balance for high and long flight. Squeezes down easily to fit in your pocket for extreme portability. Great for kids since the soft material prevents injuries. Batteries in the center ball are not replaceable. Comes in assorted bright neon colors (sorry, no individual choice of color.)
