Those of you who make gift bags to give out at concerts, what kind of bag do you suggest that meets my needs? 1. Can hold up to 4 playing card sized photocards and a few stickers. (They fit in 3"x5" but not for that many items.) 2. Easy to open/shut. The ones I used before arrived self-sealed with a really strong zipper seal, which I had to pry open one by one. I wanted to avoid this experience again. Thank you! kpopthreads
