Was super excited to find this product in the exhibition but I was super disappointed after use for less than a week, the ink flow was VERY VERY bad, I need to draw a few lines on my hand to get a smooth ink flow every time it stuck （I need to draw on my hand at least 3 - 4 times to finish one eye), so annoying !!! When I complain at the counter, the sales assistant teach me to use tissue to press the brush tip, say it would help to induce the ink flow for new ink pen. After try, is sucks, the brush tip split..... I will not buy any product of this brand, their customer service is sucks either, got bad experience when complaining about the eyeliner. VERY DISAPPOINTED !!!
