The lipstick consists out of 2 separate sides: one side a lipglossy thing, the other end a lipstick.
First, you apply the coloured glossy lipgloss. You let it dry a bit....
Then, you apply the colourless lipstick.
And indeed, it stays on for hours and hours, even when you eat or drink. I applied it for a day trip last week, was hot, drank a lot, had lunch, and after all that, most of it still remained on my lips!
I must confess, you do 'feel' it more than a normal lipstick. But the quality is remarkable.
It comes in a small variety of shades and I can totally recommend it.
