Looks good - not sure of funtionality.
Size: 12x0.5x7.5, Color: Black
I returned this bag because while, straight out of the packaging, it looked really nice and felt good in my hands, the material looked like with multiple uses and being manipulated and handled, the glossy coating might be apt to split and crack over time. Also wasn't sure how practical the closure would be with items in the envelope style purse - so ordered it to figure that out in person. That coupled with the fact that I no longer needed for the intended event I purchased it for, the iffy quality made me not keep it for future use.
