This is Tenyo's "Psychic Key." The item itself is in good condition, but the packaging has some minor scratches. Please check the photos for the condition. The effect: You show a smooth, plastic key. When you rub the tip with your finger, grooves appear on the key. Then, when you rub the grooved key, the grooves disappear. Finally, the grooves increase, and the key ends up with grooves on both sides.
