It is nice to have a zipper ease stick on hand. I feel a smoothly operating zipper extends its lifespan. This stick is more like a beeswax than a flaky bar soap consistency.
Basically I got the "grab bag" to have a few in the sewing chest in case of need. What arrived is a good assortment of lengths and colors. Three were heavy duty and separatable, they ranged in length to short like for a zippered pocket, to long like you would use for a cushion slip cover. Some were metal teeth and some were resin.
I was in a pickle because I had a zipper slider that I needed to replace that I had never seen before. I googled ‘zippers’ and saw the catchy ZipperShipper name. I told them my predicament and they said ~ oh! This is the one you need! ~ Sure enough they were right! Many thanks to the team! I ordered a few extra for future use🤓
I bought a length of sturdy #8 zipper and four sliders, to fix a worn-out zipper on an old but still-useful backpack. (I think the original pack used #5 zippers; most of them still work but the big compartment gets a lot more use). Your website has great info about best weights to use, and how to make a bag-type double zipper, and great selection of sizes (and colors for lighter weights), and fast delivery. As for DOING the replacement, I find the original zipper was sewn early in the assembly, ends covered by many layers of stiff fabric and webbing! It's going to be a tough reach for our little sewing machine. Worst case I'll hand sew it (doesn't have to be beautiful)...I'll figure it out. Your brand-new zipper is my best possible starting point.
I never even knew this type of zipper existed, until I was asked to replace a broken slider. I went right to your website, found what I needed, and also found one of your videos explaining how to replace it. Thanks!!
