Capsule Plarail Sound Signal Station Four different sounds play while the button is pressed. ・One of the screws on the back has rust. ・There is some yellowing overall. ・There is some corrosion in the battery compartment, so there may be some difficulty with contact. Please understand the above points. Batteries are LR44 x 3. The battery contacts have been cleaned a bit with a file, and I have confirmed that the sounds work with batteries inserted. Please consider.
