Review on [2-Pack] Black Stretch Card Sleeves Stick On Wallet for Cell Phone - Adhesive Sticker ID Credit Card Holder for Back of Phone by Silvia Morales

They work as described although the stretchy fabric sags a lot over time so I can see why there are 3 of them They will also come loose if you apply enough pressure, it's those right amount so they dress up It will just fall off either way and come off cleanly without leaving a mark which I like so you don't have to line up the next one perfectly to hide the sticky. lol Overall I like it but the sagging fabric is starting to get on my nerves. It makes sense because I just didn't think of it, so it's not that bad. BUT for a trial run to see if you like a product like this, that's great.
