Postal Mail Box

This is a Bote-bako (a type of transport box) with a post office (〒) mark, believed to have been used by the postal service.
It is quite old, with some cracks on the bottom, the net is not entirely intact, and there is some rust, but it has a great atmosphere.
The rusted areas have been treated with a transparent rust remover to create a protective film and inhibit further rusting.
It is heavy, likely due to its steel frame.
We believe this is a very rare item.
