Toll-designed part, I've never seen this functionality (Ring Binder Envelope = bag wallet =) in a store, and also priced really cheap. Only a few minuses for processing: 1.) The zipper internal pocket is useless because it does not close, no matter what direction one takes him; 2.) I do not understand why a strap is recommended to - I see that is no way to fix such a (fortunately I have not bought it); 3.) The plastic stinks quite long ... 4.) The circumferential zipper looks pretty fragile - I hope (* knock wood *), he still holds some time ...
