Aritaum's Mono Eyes Soft Knit

In the case of Arictaum, Mono Eyes is their flagship product, so there are popular shades, but personally, I do not recommend the Soft Knit shade for summer. That is because it doesn't show up very well, and the color itself seems to suit spring or autumn better. It can make you look hotter if applied on its own, so please use it with caution.
