Are functional

I was used to choose very thick pockets to properly protect my previous smartphone, I have no choice for my Xperia Z3 to take a very slim.
I chose it because the rails are kept continuous over the entire length of the smartphone (stiffness = protection). The phone is also super well maintained in these rails and can be removed easily without scratching or cracking the phone keeps track of (as it happens with some pouches).
The soft leather is of good quality, the folds of the flap does not mark the slice. The interior skin does not seem to get dirty too quickly (I had to use the phone with my dirty fingers tinkering, and whew, inside the pouch remained clean)
The magnet looks great set and I'm sure it will not break quickly.
(Previously whenever I changed pouch was that either the pins or maintains the magnet were broken.
I only wish other colors available

Conclusion: good product I recommend !!!
