That wing with the eye in it is creepyawesome 😀

But 3/0 brushes ? That's not that small, honest..... 😁 The smallest I sell are the Reaper Miniatures 40/0 ones, especially designed for doing the pupils of the eyes on 28mm scale figures. Although the smallest that people sensibly buy are 10/0. A lot of people forget that the perfect brush would have a tiny point but a huge belly so you don't have to keep dipping back into the paint (of coffee....)
