I bought this product a year ago in Italy and didn't even use it much because it seemed too complicated to layer it over another mascara. I then tried using it on its own and was amazed at the result, no Lash Blast or Diorshow mascara gaves me that same length (which is weird because the mascara is supposed to volumize, there's another one called Lengthening Top coat mascara which I haven't tried yet intended for volume). The brush is rounded and similar to Givenchy Phenomen'Eyes mascara's brush but I think it is pretty easy to use. I love the shiny purple tube as well, I will definitely repurchase next time I'm in Italy. The cost is 7.20€ but I believe I got it for cheaper (KIKO often has sales).
