What is it?
Memebox is a South Korean based cosmetics company that sells mystery boxes. At one point, Memebox put out certain items in their shop to sell (Or was it more like a pre-sale? I can't recall.) and allowed Memebox users to do a preliminary impression of the product by writing why they would like to receive the product. By doing so, users had a chance to win that actual product!
The THEOBROMa Premium Cacao Pack contains chocolatey goodness and claims to "purify your skin, even your pore" with no perfumes or colors.
