I don't see a metal ferrule, as in other brushes - how do hairs stay in place?

Our Artis® brushes represent a rethinking of what a cosmetic brush should be. They are a modern interpretation of the traditional shape makeup brush. A tool should be easy to use and get the job done for which is was designed. There is no need for a ferrule these days since there are many adhesives and other ways to integrate the fibre bundle into the handle of acosmetic brush. We eliminated the need for a ferrule by the design and construction of these brushes. In fact, these brushes will keep the fibres intact far longer than a conventional brush, which often begins to lose hairs from the first moment you use it.
