This mask has three levels, that means that the level 1 gives 3x more volume, level 2 gives 5x more volume and level 3 gives 10 x more volume.
This mask has some small brushes but they are very easy and help in its implementation.
What also helps lengthen eyelashes ..
It took pictures ... just took the same levels for the end result ...
In my opinion there is no significant difference in each level, but more volume but not that exaggerated volume as 10x ..
But the marked up is not bad, just does not say how that volume which is a shame, because your brush is really good ..
