these need a zipper [SEP] i own of these now these are excellent to put cell phone chargers cords adapters sunglasses or any type of loose item that you want to keep control of it provides the contents as nondescript with an appearance that it might just be a real potato chip bag you have its very life like in appearance i keep one in my purse and backpack and the other one is used inside near my electronics i took one of these to europe with me hoping it would deter any snatch and grab attempt of my electronics i kept them in this bag my one and only complaint about these bags is the fact they do not come with a simple zipper closure and that the closure is velcro with constant opening and closing of the velcro it wears out i hope the manufacturer would read this review and make these with a zipper and they will have a winner and get stars from me for sure
