I don't like the eyeliner as an eyeliner. Instead, one day, I discovered that the ease with which the eyeliner smudges makes it look like an alright eyeshadow, blended in with my actual eyeshadow. The dual colour that I got is the brown one so it works quite well. Note that I don't like heavy makeup at all, so this won't be for everyone.
I got the white one and I use it for highlighting the inner corners of my eyes. It's a pretty pearly white color. I use the end that looks like regular eyeliner. There's another end with a spongy applicator that's soft, but I don't really have a use for it. There used to be a Missha store in the mall near me, and I really miss it. They had some really nice South Korean cosmetics at decent prices. ( :
This product is a combination of eyeliner and cream eyeshadow. The eyeliner is an automatic pencil that is shimmery, soft, and a bit too emollient to be highly pigmented. The cream eyeshadow is contained in a tiny tube that screws out with a sponge/smudge type applicator. Sadly, the sponge is very rough and it makes me feel very uncomfortable to use it on my delicate eye area.
I have this product in pink and purple. The liners are nice for lining the lower lash line. It's pretty cheap in Korea but I don't know if it's worth paying a markup and for international shipping.
