I bought this product in a Mall in Malaysia. Its really cheap, around $ 5.00. This marker liner is easy to use, dries fast , very pigmented and easy to remove. The staying power is quite good as its not dissapear right away, but more like fading a bit.what i dislike about this product , its not waterproof and smudge on under eye area after a while. (my eyelid its not too oily nor too dry ) i dont recommend this product to draw waterline. Even i find it easy to use but since the shape of the pen is chubby as it claims, it may hard for some people.after all, this product is good to try for beginners, since its affordable and perfect to make thick or thin or wing lines.
