Kylie Jenner's pop-up shop has only been open since Dec. 9, but fans from all around the world have been excitedly mobbing the Topanga Westfield Mall [1] to snap up a memento from the star's store (and, of course, to see that incredible wall of Lip Kits [2]).

If you haven't been able to make it out to California, you might not know about the strict rules of the "Kylie Cosmetics experience." The team at Racked divulged the exhaustive list [3].

As you can see, there is to be no sitting in line as you wait to get inside. This seems like a reasonable request until you realize that some fans wait up to 10 hours for their moment in the Kylie pop-up shop. That blissful moment, by the way, is limited to a brief 20 minutes, during which you can only purchase up to three of each item. Did you want to buy an additional product after your 20 minutes have passed? Too freakin' bad: you'll have to go to the back of the line and start over.

But perhaps the most discomfiting aspect of the experience is saved for last. Racked shared that there are also no prices listed anywhere in the store, so you have no idea what you'll be spending until you get to the register. Unless you have a Kylie-sized bank account, that could get a little uncomfortable . . . we think we'll stick with shopping her online store [6] for now!
