This is a simpler version of the cryptex device. The core of the cylinder is empty and it is used to store valuable objects. The device will only open when the correct combination of letters,numbers, etc. is achieved. My design is almost impossible to open without the proper heavy tools. The cryptex is missing the letters written on the squares on the smaller cylinders.
