This is a triangular case for storing triangular paper, which was stored long-term at my parents' home.
There are signs of use such as thread fraying, scuffs, dents, wrinkles, and dirt. It seems to have been stored with butterflies packed tightly inside the triangular paper, as there is an odor when the lid is opened and the case is brought close to the nose.
The metal clasps open and close without issue. There is a belt loop on the back. The triangular paper has been discarded and is not included.
Please allow for slight variations in size.

Please check the condition by zooming in on the photos. We appreciate your consideration if you accept the odor and condition.

*Butterflies are for display purposes only.
