AP Brush: Wargammer Small Drybrush

From Army Painter:

This is a very popular brush and as its bigger brother, this spectacular drybrush has a 43 degree angle cut to make it no less than perfect for drybrushing small miniatures.

The size of this brush is designed for drybrushing areas of a model, like chainmail or a weapon - and not neccessarily the whole model at once.
