Since I put much emphasis on original accessories, I, the CP-323 have bought from Nokia. That there were supply problems, however, I had to rely on the local market around the corner. I've bought the black model, the gray bag was nowhere to be found. The black bag I used to last about 1 month I Today, the gray model grew me. Both bags have in my opinion erheblliche quality differences, my black bag is elastic and of much thinner material than the gray. The gray is processed somehow-quality and better, the only downside is the phone you get more difficult to get out. I have no idea why the two differ pockets so! I would buy both bags again, but would prefer access to gray. The disadvantage of both bags is the open side and the subsequent lint on the screen. Both bags are for the price in order and protect (despite Offner page) the phone very well. In your pocket, the N97 fits naturally then worse.
