I've always wanted to try AOU products, but since it comes in a stick form, I wasn't sure how to use it... I thought it would be a bit wasteful to buy a lip brush just for this lip product ㅠㅠ... Then I heard they were releasing a new version with a built-in silicone tip, so I bought it right away! It is a bit inconvenient to have to wipe it after use, but I really liked that I could do lip makeup without carrying extra tools ㅎㅎ!! When I tested it at an offline store, the color looked pretty, but when I applied it again, it came out more red~.. After applying a base and layering it again, I got the color I wanted. I'll use it well!
