Based on my impressions after delivery I have to say though, that I would not order this bag again. The upper part with the zipper is quite simple with a few stitches sewed the bottom leatherette part. At the seam line you can easily see through to the other side. The artificial leather has an unpleasant odor and acts as if it would flake off when usage is low, and then release the material structure behind it.
The bag is rather bigger and could probably comfortably accommodate 8-10 keys. However, I doubt whether you will really have continued enjoyment of the product at this load.
Conclusion:
The rather low price is mE for the quality and workmanship is still too high. As giveaway might be tolerable when buying a Fehlinvestiton. Prefer to invest 2 euros more in a real leather bag!
