Strange odor upon opening, magnet zap cards

The product has been slow to arrive ... My return after a few weeks of use:
- Chemical Odour stinging opening.
- Magnetic closure has demagnetized cards parking
- Inside pocket: I can put 2 credit cards but no more
- Location of the iPhone: the plastic shell in which one has stuck his iPhone broke after a withdrawal. In fact, to install my iPhone in the car, I have to remove it every time the hull. It is difficult, we must twist the plastic and have thus slightly scratched the phone on his side, that rub against the plastic.

Positives: texture of the cover, use "stand", protection from the weather
