I bought this to use for an egg white mask, but its real name is actually a Bubble Maker! If you move that handle up and down vigorously, bubbles are created. I used to use it a lot a while ago, then put it away, but I've been using it again lately! Haha. It does a really great job of fulfilling its role as a bubble maker. It's hard to even spot an Etude House store these days~~
