Memebox is the #1 Korean store and it specializes in beauty boxes. It's not a monthly subscription, so you can pick and choose your boxes. There are many types of boxes to choose from according to themes. The boxes start at $15 and run out super quickly so it's best to snag one as soon as it catches your eye.
Here is the unboxing of Memebox's Scentbox #6 Sweet Shop.
