This is the Kamen Rider W Cyclone Memory. Functionality has been confirmed when the memory button is pressed: - It lights up when the button is pressed. - It says "Cyclone" when the button is pressed. I no longer have the belt itself, so I haven't been able to confirm how it works when attached to the belt. The batteries are the original ones from when it was made. [Condition] There are fine scratches overall. It has been stored at home for a long time and was played with by children. Please refrain from purchasing if you are sensitive to used items. Thank you.
