I recently purchased this iPhone 6s/6 Leather Case by Plenty with a Card Slot. Its made of high quality looking leather and seems to fit very closely to the phone, unlike some of the plastic iPhone cases I previously used. It also has a Credit Card Holder on the Case and comes with a Stylus Touch Pen and Walnut coloured Gift Box. I don't know if I will be using the card holder feature but it seems to be pretty snug (which is a good thing so your credit cards don't fall out!) One thing I have noticed - the case comes up to the edge of the glass on the screen, so if you put it down hard on a rough surface and don't have a screen protector, it may scratch. Just something to be aware of.
