Ultraman Tiga Color Change Series POWER CHANGE ULTRAMAN TIGA I have kept this in a dark place at home after purchasing it. There is some color change on a part of the outer box, but otherwise, there are no noticeable scratches or stains (see photos). The color changes from Multi Type to Power Type at approximately 35°C or higher. I have not opened it for many years, so I cannot guarantee whether the color change will still work. Please consider this only if you understand that there may be other signs of aging. Please feel free to comment if you have any questions. Thank you.
