Discolored edges after a year

While I was happy with the printing when I got these a year ago, I never got around to using them until now. They have been stored in the plastic bag and the box they were sent in, inside a closet. I looked at them today and it looked like there was brown dirt around the edges of the labels. Thinking maybe it was just the first ones at the top of the roll, I looked at the entire roll and they're ALL like that, so they are now unusable. Must be the glue that was used...it's a brownish discoloration. And being that they're clear, it easily shows up. NEVER AGAIN!!! I'm done with this company.
