I've produced 5 mint tin versions of Laser Bounce in preparation for the upcoming PAX Australia where it will be part of Collaboratory: a playtesting space for unpublished designs.
I printed the labels on 160gsm paper (which is about as thick as my printer can handle) and superglued them onto the mint tin, which worked quite well. With just the right amount of glue it didn't seep through the paper and sticks firmly.
