No-tool zipper replacement
This product allows you to replace a broken zipper slider without having to buy and install an entirely new zipper. The slider on my favorite alpaca sweater disintegrated in my hand. I went to a tailor and she wanted $40 to replace the zipper and in addition, I had to supply the new zipper. The existing zipper was fine but no slider. The Fixnzip costs under $13 with shipping and did the trick.
It is a clever slider with a clamp built in so you can install it by slipping it onto one side of the zipper and then the other and turning a thumbscrew to tighten the clamp. It worked perfectly. Detailed instructions are on the Fixnzip website.02/22/19
