Review on Sinjimoru Credit Functioning for iPhones and Androids by Joseph Quintana

I love these things! They are perfect as they fit almost any sleeve and hold more cards than any other sleeve/holder. I carry about 6 cards with me. A word of warning though - one of mine snapped after just a few days of use (it's black with a leather back). Everything just collapsed. I think it's because of the leather base (nylon doesn't stick to this material as well as other materials). In any case, I liked this article so much that I immediately bought another one. Revain was so friendly that I felt uncomfortable returning it.
