The Master Lock Fire-Resistant & Waterproof Document Bag is a high-security personal pouch engineered to safeguard critical records, identity papers, and digital media from devastating fire and water accidents. Sized precisely to fit standard A4 documents flat without folding, this heavy-duty pouch is ideal for protecting cash, passports, tablets, and external hard drives. Built using a multi-layered material composition, it features a thick, non-itchy silicone-coated fiberglass exterior that deflects direct flame heat alongside a specialized waterproof layer to protect contents from emergency fire sprinklers or flooding. As shown in the visual structure, the top fold-over flap is secured by a integrated mechanical key lock, providing a quick layer of privacy and theft deterrence that keeps unauthorized hands away from your confidential assets.
