Thank you for stopping buy.

I have this silver colored, the bottom part of the box is very thick and heavy

The size is (15x11x8 cm).

X ray couldn’t reach through it at the airport but it is definitely not silver.

It has wooden insert on the inside that actually comes apart easily.

It has a CPO mark at the bottom (occupied Japan as far as I’ve researched).

I would like to have more information about it, especially the pattern on top, box’s purpose and possibly value.

Thank you in advance
