Okay, final update to this. I did reach out and, in short, he essentially said I was zipping incorrectly. Or perhaps, that I need a special method to zip his bags. One of the two. Since I am the sort to naturally assume fault - like, I don't know, even though I've lived for several decades perhaps in fact I don't know how to use a zipper?? - I did get another adult (my husband) to attempt, and I guess he doesn't know how to use zippers either. 🤷🏾♀️ I found the best way to use this zipper is to keep the tab out (I do not prefer this look, but okay), and be careful not to open the zipper all the way. Even then, it's not great, but it's less of an issue. He said if it's really a problem, I could get a cobbler to add a "metal rectangle to block the zipper" to prevent it from opening all the way. Perhaps I will take it to a cobbler to fix what Massaccesi could not initially do correctly. I made a video for him, and will share it with you in case you are curious.
I mean, it's not the end of the world, but I am dissatisfied. I don't have a single bag with a zipper as bad as this, including those that have a tab you can pull out, and including cheap things from Target or
Amazon. Meaning, even cheap bags have better zipper construction. I'm now less angry about the zipper and angrier about him putting the blame on me as someone who does not know how to use zippers as opposed to admitting the faulty construction. I had been curious to try this custom maker for over
two years, but now regret the purchase.
