USE
It is absolutely not difficult to handle, the brush is sold as phenomenal but its use is standard: first the concave side that separates the lashes into small groups see eyelash to eyelash would like a comb comb teeth tight on hair, then the larger convex side for depositing a greater amount of mascara on the lashes separated.
This is to rotate the brush during use, naively.
EFFECTIVENESS
The substance is easy to apply fluid. The volume is very satisfactory, and deployment of eyelashes is indisputable (those who will say the opposite either failed to use the brush or the chance of having too many eyelashes) and are actually long, more than with the Great Lash Gemey.
HELD
The holding is good. However, as I use it in combination with a waterproof (Volum'Express Rocket Gemey), I can not talk about her outfit daily.
LIFE
I will not comment with certainty on its lifetime, although in terms of its consistency after 2 weeks and other mascaras I tested, I predict it six months before drying services.
