Etude House play crayons are supposed to be versatile like the play pencils so I use this as an eyeliner and sometimes eye shadow. It works great except the crayon size is thick (as seen in photo) so it doesn't work as a thin liner unless you're careful and you sharpen the tip regularly. But personally, it doesn't bother me. 

Doesnt last as long as i expected it would. :/ But its rich in color.

nice colour and easy to carry around. 

LOve it! It's easy to use, blendable and pigmented! Works very well!
