It was working fine until recently, but when I checked it today, it stopped working. It is a junk item. Since it is a very old product, I would appreciate it if those who understand retro items would consider purchasing. Size: Approximately 9cm x 8cm Measured at the longest points. On the back of the bus stop, there is one spot where the plastic has melted due to aging. Please assess the other minor scratches, etc., based on the images.
