This putty can be stretched, pulled, bounced, manipulated and stuck to things. This is the world's first translucent putty, allowing light to transmit through it. Each UFO comes with a brilliant flashing light module, and when lit up inside the putty, the visual effects are stunning! There are several colors of Putty, distributed at random. UFO is about 3'' in diameter and 1'' tall. Flashing module continues for 20 seconds at a time.
