Capsule machines are vending machines that dispense small, sealed capsules containing toys, collectibles, or other novelty items. These machines are often found in public places like arcades, malls, and amusement parks. Users insert coins or tokens, turn a knob, and receive a random capsule, making it a fun surprise. The concept originated in Japan, where they are known as gachapon machines. Capsule machines have gained popularity worldwide, appealing to both children and adults who enjoy collecting the items inside. They offer a unique way to experience the thrill of chance and discovery in a compact format.
