Box Frame - For Miniature Decorations and Collections

This is an item for organizing my belongings.

I purchased this several years ago with the intention of making a miniature box, but it has remained unused since then.
The interior lining is already completed.

I will also include cut shelf board parts that can be used to create shelves, so they will be delivered together.
Would anyone be interested in making something with this?

Thickness: Approx. 36mm
Outer dimensions: Approx. 180mm x 150mm
Window dimensions: Approx. 150mm x 120mm

Please refer to the photos for the condition.
Please note that I plan to use postal delivery (post-to-post service).
Kindly understand that it will be delivered in an envelope in its current state.
