Seriously - what is up with Coach zippers??

I noticed my boutique Zoe's zipper is smooth, but my MFF one isn't, it gets stuck at the most open position, drives me crazy!! Maybe there is something to the brass zippers being less sticky than nickel... interesting.

Sounds like the pull might be going beyond the last teeth and getting misaligned. One trick would be to take a needle and heavy duty thread and make a bunch of stitches around the last few teeth, to essentially make a new stop point, so the zipper pull does not go to the problem point.
