Need secure bags for cash deposits or valuables? These ControlTek SafeLok bags are a top choice for retail stores, banks, and businesses. Each white bag is 12\ x 16\ and can hold up to 3,000 bills (about 3 bundles). The best part is the security features: they use a simple 'Press2Lok' closure – just press to seal, no messing with strings or staples. But if someone tries to tamper, the bag shows it. The seal has special ink that turns red with heat, shows a 'VOID' message with cold or chemicals, and has hidden micro-printing. There are also random printed lines to prevent 'cut and replace' tricks. Each bag has four large, easy-to-scan barcodes and sequential numbers for tracking. The inside has an anti-static liner so bills don't stick. Comes in a pack of 50 bags. They're reliable, easy for employees to use, and give you peace of mind when moving cash. A professional-grade solution for loss prevention.
