I've read over the years, about people using and loving the Eyeko Skinny Liquid Eyeliner. I've heard it compared to my HG K-Palette Eyeliner and other Japan brand eyeliners.
For those who haven't heard of these yet, here's a quick overview. Originated in London, I believe that at one time it wasn't easily available in the U.S. and elsewhere other than Europe. Again, I'm not positive on this as I hadn't been looking to purchase these at the time. I discovered in the last 6 months to a year that it was available at Sephora. In store, there is only black available, so I had purchased that a while back. It is a pen-like eyeliner, similar to many Japanese brands as well as Revlon Colorstay and Physician's Formula.
I recently discovered that there are other colors available online at Sephora so I decided to pick up Navy and Purple.
When I first purchased the black one a while back, I have to admit that I didn't care for it much. I felt that K-Palette worked for me much better since the K-Palette pen lines your eyes with a much finer line than Eyeko. I was lured by the thought of being able to use navy and purple eyeliner, which is why I decided to purchase Eyeko eyeliners again. Unfortunately, I am not impressed and am rather disappointed. I was hoping for some brilliant eyeliner colors but they come out so dark that you really can't see a distinctive color difference. When compared side by side with the each other, you can see how similar they are to each other. (B=Black, N=Navy, P=Purple)
I also find that Eyeko eyeliners do not glide on like the way K-Palette does. I was willing to overlook the differences if I could get brighter, more discernible colors in the colored eyeliners so it's unfortunate that it doesn't work out for me. I'm sorry to say that these were a thumbs down for me.
