Looking to make a cosplay of Kaiji, specifically his look from the Restricted Rock Paper Scissors arc. I've sourced most of the jackets patches except for the blood chit on the back. Pic rel is the best reference I've found but it's shockingly low res.

I can have the blood chit printed if I find a high quality file. If anyone knows where I can find a high quality file or a premade blood chit to buy I'd really appreciate it.
