There are plenty of cases in the thread without flaps w/ pictures... Pretty much every card holder available is shown in that thread - o ff the top of my head the oniki, hex, something tokyo. etc..
I don't have this version for iPhone 6 but I used the one for iPhone 5/5s and it was VERY thin, I think it only offers basic protection and the pocket can only fit 2 cards max, maybe 3 if you force it (I only used it for one card).
