From the mystery handbag set, this is the Alice handbag.
This set contains a total of 16 pins.
It is a little over 1" in height.
The Cheshire cat's pink tail serves as the handle on Alice's bag, which features her signature blue and white apron dress. It's decorated with red and white roses and a black bow.
Below the pin post are two boxes, one with the traditional Disney Pin Trading logo and the other with the FAC (c) Disney, made in China.
DLR and WDW have now released it.
