Seems like you're great suitcase but I just had a major panic attack because I received it locked and there were no instructions. I went to the product page again and saw that five other people had the same problem. When you receive it it will be all set to zeros and the zippers will be in the locked position. All you need to do is that little square that has a keyhole in it and says tsa007 on it, slide it to the right 1/4 inch and it will pop out the zipper locks. Then you can get inside to retrieve the instructions.
