Review on 📱 FRIFUN Stick on Phone Wallet, Ultra-Slim Self Adhesive Card Holder Credit Card Wallet for Smartphones RFID Sleeve with Extra Tall Pocket, Gray Plus - Complete Coverage for Credit Cards & Cash by Bill Russett

Update: I ended up taking it off because it got obscenely dirty, I wiped it down with soap and hot water, a couple of times it just wouldn't clean. The paint has been scraped off the button. But the "leather" part stayed in good quality, so here it is. I ended up getting a waterproof case and stuck it on the back of my iPhone X and I love it. It holds about 5 cards before it becomes difficult to zip up and is stretchier than I thought it would be without being a cheap quality fabric. (It looks like canvas but behaves like spandex)
