I've had this case for several years and am surprised at how long it has lasted. It has been tossed in various bags and transported to many places without losing a single stitch or tearing it. I started using it for business cards, now I keep birth control in it. (For the record, I have a Yaz backpack and it has room to wobble.) I particularly like that there are hard plastic reinforcements on the sides and bottom that stay square and won't wrinkle over time.
