To use the eyeliner, you need to take out some of the powder and mix it with water. Then, you will need a eyeliner brush to apply it to your eyes... What a troublesome process. The problem is 一個要用水開既eyeliner, 即係唔waterproof架啦. 果然, 用唔夠2個鐘已經開始甩, 眼角位黑唒化唒. Absolutely impossible to be used in summer, especially if your eyelids are oily. 好失望個counter sales冇講明, sigh...
