Here the airbrush brush to shine. They come in 5 different sizes, are flexible and resilient. Practical strung on a ring in order not to lose, they keep me since the Bestellugn faithful service. With the tip I have something to take care to not inadvertently damaging example Resin figures, but with practice it's no problem. The bristles are, as I said, to get hard enough to paint residues from crevices and recesses without damaging the miniature.
Since I do not have an airbrush, I can to the intended purpose of the brush not say much. But for my purposes, they are ideally suited.
