Ouch!
Not sure what you were doing, but whatever it was, you weren't very good at it
Those look like Walgreen's version of Steri-strips....good things to have.
Only difference, for me, is that Steri-strips are sealed a little better, so they last longer when stored.
No, they don't go 'bad', per se, but the packaging on others allows more air in, so they deteriorate quicker over time.
Also, once applied, Steri stays on longer.
I have used a
lot of Steri-Strips...even to keep an open wound together for months after surgery for MRSA...
