I have a very sharp metal zipper in my new purse, how to make it "softer"?
You should have your purse zipper replaced to solve the problem once and for all. You can actually replace it yourself once you buy another zipper that's not as sharp. To sew the new zipper in neatly, it's best that you use a machine.
It's actually inside ur purse right? Maybe wrap some form of tape around it. Ya it may be ugly but if its inside not that big of a deal.
Beat it with a hammer
