The final iteration in the Zip Clip series. This lock with no key is the most advanced, and secure, that I have ever made. It is simple to put together, and easy to open (When you know how). But it will make thieves all around scream in rage as they try to figure out how the thing works. It is sturdy, making it resistant to breaking, whether accidental, or intentional. Here is how it works:

- Put together Side 1 and Side 2, with the two zippers on your backpack between the two.

- Push the bottom, logo side down, through the hole on the top of the "glove".

- Clip on the cover for the bottom. This will NOT be removed in the future.

- Slide Side 1 and Side 2, now put together, inside the top of the "glove".

- Turn 90° and pull up.

- Push the bottom up, and turn 90° to lock everything in place.

Now, it should be impossible to open your backpack until you reverse the steps above. Try it on a friend! See if they can undo this lock. Take it into the wild, and test the steel of hardened criminals. It sounds overwhelming, I know, but with a little practice, it will become like second nature. Stay safe!

Warning!!!

While almost impossible this device can be opened by an outsider as it does not lock. It also can be broken and is not guaranteed to protect your belongings against every individual.
