Vintage Japanese Travel Metal Ashtray

Travel, because I believe it’s meant to slip into a front shirt pocket! (But what do I know). Very used and with discoloration. The closeup is of some metal on the side which has separated. Fully functional and so cool to whip it out when having a smoke. 3-1/8” x 2-1/8” Copper patina Bundle & Save. Peruse my 2,000+ item selection.
