I love these because they are small but hold my credits cards (2), I.D., Metrocard and money while being slim, sleek and uncomplicated. However, I had to knock off a star because I had to resew the Velcro back on. Due to the wear and tear of taking it on and off it started to rip off after two months. But they're so inexpensive I'll just reinforce the Velcro myself. The material can withstand the extra treading and wear and tear.
