The effect of this mascara is similar to benefit roller lash, except this is waterproof and has small fibers to add length. I don't always like fiber mascaras but the fibers in this one are not clumpy. This lifts my lashes and the curl stays all day. My lashes are not left straight by the end of the day. Like all asian mascaras I have tried, this is hard to remove. The best way is to remove this is with oil first and then cleanser. I would definitely repurchase this.
