The envelope is ok for the price, but has a small hook

I have the envelope (transparent) for a long time in use, shortly after buying the iPhone 5 in November 2012. The function of a protective sheath is given here only conditionally as a pocket carrier. As yet squeeze now and then crumbs and hooch between Case and iPhone, it is inevitable that permanently by the movement of the sheath perpetuate itself firmer "objects" in the aluminum casing properly and cause deep scratches. On white iPhone you see the most, since these scratches then be more black and especially conspicuous. My friend has a black iPhone, but the iPhone has noticed in a separate, hand-knitted sock in her handbag, there's nothing to me right away.

For the price of € 5 at the time that I have paid for Cyber ​​Monday before Christmas, ok, but very expensive in retrospect, as the value used my iPhone will be moving very strongly downwards. And I only wanted that the iPhone is not the same fate as the time of 4 with the curb.
