After carrying my Maratac daily for almost two years, I noticed it was gone, and found a perfect Maratac-sized hole in the bottom of my pocket after a very active day 

I’m thinking of replacing it with the copper version.

I was wondering if the copper version leaves behind any residue on fingers or clothing. Especially after developing the patina? It will be carried in suits and black tie, and any residue on those would quickly ruin the evening.

Thanks!
