Hey guys it’s, your girl Juliet! Comin at you, to tell you about what we use on our handmade leather backpacks, purses, and wallets that include zippers. What kind of zippers? We turned to Riri zippers for that luxury touch. We believe that Riri zippers are the best and most reliable quality. Some popular companies that also use Riri zippers are Prada, Dolce & Gabbana and so many others. Therefore, your trip is going to prada slide very smoothly, that joke didn't though. While Riri zippers are being made they are able to withstand 160 lbs of pressure at the end of the process, so no pressure...well you can put pressure but ehhh i should just zip it. Anyway, we use Riri zippers to make sure you guys are able to use our products with ease and allowing you full control of the zipper, because we all know you get frustrated when they get stuck and you're just yanking it until it fixes itself. I hope this information gives you more knowledge about what is being used in the products you are receiving and purchasing. Thank you so much for your time and support you are giving us! Hope to see you soon! BYYYYEEE!
