It's been a year since I bought it, and it not only keeps the curl, but the liquid doesn't dry out. I was impressed because I often end up throwing away department store and major mascaras because the liquid dries out before I can use it all. It's also a pretty black color, so it really enhances the power of your eyes. It doesn't smudge, even in the summer, and can be easily removed with regular cleansing. The cost performance, finish, and ease of use are perfect, so I gave it a perfect score!
It felt good right after I bought it, but after using it a few times, it started to clump. It doesn't feel particularly bad, but it's neither good nor bad...

The brush is small, making application easy, and it has great curl retention. It separates the lashes beautifully and applies thoroughly from the inner corner to the outer corner, so it looks like I've created fan-shaped lashes, and people often ask me if they're my natural lashes. Sometimes after oil cleansing, a thin layer remains on my lower eyelid, but before I remove it, it stays smudge-free until the evening.
With regular D-UP mascara, I don't know if it's my eyes or my skin that causes it to flake off and hurt my eyes, but this one doesn't! It keeps the lashes even and is easy to use.
