Reddit mentions of Durapore Surgical Tape, 2" (Box of 6 Rolls)

Here is the tape that I use, I just tape around the outside edges of the patch in a square. I usually put the tape on the edges of the patch first (with the film still on the patch, so it's not sticking to stuff), then peel off the film, and then transfer the patch to my back after that, because I'm not that coordinated with taping behind myself lol ;) i have found that tape can really hurt when you take it off, and even rip off skin! So this tape is gentler, but also sticky enough to actually stay on for 12 hours. Also, you're supposed to take at least 12 hours off between patches, so your skin can breathe, just FYI.
