Hey thedeathparade, I actually do not zip mine open/close. I purposely wanted a bag with a zipper, but I find I do not ever zip it HA! How old is your Tivoli? *sigh* I am wondering if I just did not notice it when I bought it. Maybe the glazing on that part was really thin, and I did not look close enough. If they give me an option to replace, I will DEFINITELY be looking over my bag more carefully just in case. She was my first bag, and I was hoping she would last me forever!
Mine is only a couple weeks old and it is the first bag I am paranoid about. I have seen from pictures that the top trim has a few potential problems with wrinkling and losing shape so I am been so careful even zipping it. I hope they repair it or replace it for you!
