This "wallet" easily holds a passport and several credit cards. The Velcro closure was very effective. The gray material is flexible, but not especially attractive -- but one does not buy this item for its looks. It was used frequently over a two-week trip and held up well. It is much more durable than the same company's less expensive, smaller, open-end envelope style that my wife used. I have not tested this wallet for its electronic protection, but I have no problems in that respect.
