I recently got one of the Pirata BV's during the Pulse sale. The print is just about as perfect as you can get with almost the whole scene on both sides. HOWEVER, while playing with it, I've noticed that the zipper is really hard to open. It closes just fine with nary a snag, but you have to pull really hard to get it open. I am afraid I'm going to either bust the zipper or at the least pull the zipper pull off. Is this a usual thing that's easily fixed or is it just a faulty zipper? I have to have a zipper top otherwise my things just fly out whether I dump them or not. Any suggestions? I don't want to return it. It's a great bag and the other zippers work fine.
