Hi all, I was wondering if anyone had experience with hookless zippers here, and might be able to help me? The other day I zipped up my jacket a bit too quickly, and I guess the teeth were not engaged properly. I basically couldn't pull the zipper down! Luckily, I was able to squirm out of the jacket somehow, but the only way I was able to unzip the jacket was forcibly. In hindsight, I probably should not have done that, but I acted in haste as I felt a little panicked! I think I may have damaged the zipper though, because it will no longer zip up and down (it always gets stuck on the way down now). I was able to use some needle nose pliers to squeeze the zipper together a bit, and that actually worked for an evening. I left the jacket zipped ovenright, and this morning tried it on again, but lo and behold it got stuck again. Is this something I can repair, or replace myself by any chance? I've attached some pics of the current state of the zipper pull. Thank you so much for any potential advice.
