Part round, part flat, the filbert's rounded-off tip is built for softness — it lays paint down without the hard edge a flat leaves behind, so transitions disappear rather than stack up.
It's a slower brush than a flat for straight coverage, but for anyone chasing smoother NMM or blended paintwork it's worth the extra minute per model.
Size 6, synthetic bristle, sold as a single brush. Keep a round on hand for the fine detail a filbert can't reach — see the full AK synthetic brush range.
