Thank you for viewing. Mind Flex from SEGA TOYS. This is a new type of game that allows you to enjoy a novel sense of operation by controlling a ball with your brain waves (concentration). This brainwave toy, which uses brainwaves to play, is finally arriving in Japan after a big break in the United States. This is a new game machine that uses the "brainwave detection sensor" and "brainwave analysis program" developed by NeuroSky. By attaching a device called a "headset" to your head, your brainwaves are read by a sensor, and a fan is rotated according to the degree of concentration, allowing you to float the ball up high and move it by turning the dial. Overall, it has been used very little and is in a clean condition. Battery operated. Power on confirmation has not been performed. Alkaline batteries (3 x AA batteries) required to operate the headset, and alkaline batteries (4 x D batteries) required to operate the main unit are not included, so please prepare them yourself. Everything in the photos is included. Although it is close to an unused item, it is a used item (beautiful) that has been stored at home for a long time. Thank you for your understanding of used items. If you have any questions, please feel free to comment.
