LEGO is currently running a contest where the most popular productions can hope to become officially licensed sets, and this mystery box is one of them.
What is a Mystery Box? Well, it’s a more adult version of a piggy bank, and you can use it to safely store something in there being sure that whoever wants to take it out will, at least, have a really hard time because those things are hell to open. Check out the video below to see how it works.
If you like what you see, be sure to give your support to the creator and you might end up seeing these on stores.
