Description

Disney Mickey Mouse 1-Inch Collectible Pin Lot Of 2. Condition is "New". Shipped with USPS First Class.
I have no idea what these actually are. The front of the pins look to be made of metal and glass. The back of the pin has some sort of on/off switch and a battery compartment. A bobby pin is on the back as well I guess to hold it onto your shirt.
When trying to switch it on, nothing seems to happen. I’m assuming it’s because the battery needs to be replaced. One of the pins is noticeable faded than the other.
All I do know is that this came out of a box with other vintage collectibles from the early 80’s so I’m assuming these are pretty old.
