MobiMan® Premium- Genuine Leather Vertical Punch Case with Belt Clip for Nokia E73, E71, E72, E63, C6, N8

I found this to be a very good and sober case for my Nokia E73.
At this price, it’s hard to nitpick, but to help you decide one way or another here goes:
1. Good, but not flawless build quality (a couple of short, unterminated, threads in the back only).
2. Leather smells like leather. Might not be Italian made, but it’s leather nonetheless.
3. The magnetic flap provides for a robust close and hold, but the flap design makes it easy to open.
4. Phone is very slightly loose in the case if slid in top up; much tighter if slid in bottom facing up.
5. The clip feels solid. Make sure you clip it right though; it’s easy to get your belt underneath it.
Recommended, unless you’re comfortable spending five to twenty times the price on a name brand product.
