I needed an ID case that would also hold a few essentials (driver's license, credit and ATM cards, a bit of cash) because I don't like carrying a purse with me all day at work, and most of my work clothes lack pockets for even a small wallet.  So, despite the reviews on this product, I ordered it.  I figured that I could replace the lanyard with a shorter one and dig out my needle and thread if the stitching came out.  What I didn't expect was the zipper to separate -- I glanced down while on the subway to see that the zippered part of the case was wide open,  Fortunately, nothing fell out, and I was able to get the zipper functioning again, but I resorted to using a binder clip to help keep the case closed.  This weekend I found a similar case for $1.99 at the dollar store that will serve as a replacement.  I don't know how long that one will last, but it appears to be much better constructed.
