What a fun case with all those zippers! My first reaction is not entirely correct, because it is not a lot of zippers, it is one long zipper that you can open completely. Is that really possible? Yes, it certainly is!

You do need two hands working well together. One hand to hold the case in place while you pull the zipper loose with the other. When you go around the bend, you need a little extra attention. You have to help the zipper around the bend, so to speak. But once you've done that once, it's certainly not difficult.

When you have pulled the zipper all the way open you will be amazed at the length. It is really true, one long big zipper, very cool!

Then of course the trick is to zip the pencil case back together. It is the same pulling motion only with the zip reversed. If you want to practice the other hand, then it is of course no problem to perform both actions in the opposite direction. But be careful, that requires a little more attention because you are not used to it. You automatically use the hand that you normally write with and that feels easiest first.

If you don't close the case all the way, you will see the mouth of a 'monster', hence the name.

The series has different sizes, there is a large and a small version and even a very small one for coins as a key ring. All equally fun!
