This is a glass container of the first generation Koume-chan, likely from the 1980s. It comes with a styrofoam case. I found it at my parents' house, and it was in the box as it was sent. The pink part of the lid is made of plastic. The lid is the type that lightly covers the container.

Although it is unused, it is an old item, so please consider this before purchasing.
