It's just, like... legitimate medical tape, randomly chillin' on my desk.
Albeit I've also got a sewing needle, thread, some candles, and y'know what, despite the appearances I'm not equipped to be anything remotely doctorlike.
Let me rephrase it this way; with a few things that are within arm's reach of me right the hell now, I could stitch some poor fucker up. Albeit it would be very ghetto, given that I don't even have any disinfectant.
