received this in a Rubybox. I have never been a fan of felt-tip eyeliner pens before as I found that the colour did not go on intensely enough and all the ones I have tried in the past have dried out very quickly. However, I can honestly say so far that this is the best liquid liner that I have ever used! This is so perfect for doing a cat-eye look (which I do pretty much every day), it goes on completely evenly and the fine tip allows for accurate and complete control, and it lasts all day long for me, no hint of smudging or fading. I am just hoping that this pen continues to impress and doesn’t dry up and fail me as quickly as my previous ones have. If so then this will undoubtedly become a firm faithful favourite!
