Shopping in Japan part II

This bottle contains almost pure salicylic acid. It's bought at the supermarket and is really good for people who wants a skin like a baby. The amazing thing about this bottle is that I don't think that they would sell it in the States or in Europe. One of the labmates insisted on doing our own commercial for the product.

Why do they sell gallons with 4 L of Sake at the grocery store when most of us are working at 10 pm on a friday night?
