The 7-pin locking Security Bag utilizes the most secure lock in the industry—it is virtually pick resistant to protect your cash and valuables.  Unique lock feature prevents the key from being released until the plunger is pressed down preventing users from accidentally locking their keys in the bag.  The built-in key is keyed differently with no master. Available in 18 oz. Duck or Laminated Nylon, these bags are as durable as they are attractive. The 18 oz. Duck bags can be purchased in navy; the Laminated Nylon is in an assorted pack(1 Navy, 1 Red, 1 Green).
