I use this to hold small items; I might use it for coins too if I get another one. The material is lightweight and feels quite durable (and also water-repellent - maybe even waterproof?). Inside it is light so that objects are not lost against a dark background. The seams are well finished: they are covered with a seam panel. The zipper has serrated edges on the inside; So the tongue is a reverse pull (NOT a reverse pull) and all the tongues I've seen on this type are very short. I added a drawstring for easier opening/closing of the zipper. A driver's license and a credit card or two fit in the hole, but no "empty space". It would be really nice if the bag was a little bigger or if the zipper opening was a little bigger. Then I would use it as a replacement for my wallet.
