This set includes 20 red Fortune Teller Fish, a classic novelty item that responds to body heat. When placed in the palm of a hand, the fish moves or curls, simulating a lifelike reaction. Each fish measures approximately 2 inches in length and is made from a thin, flexible material. The pack contains 20 identical red fish, suitable for party favors, pranks, or educational demonstrations about thermal sensitivity. No batteries or assembly required.
