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.

Best for

• Soft blending and colour transitions
• Curved surfaces — helmets, shoulder pads, vehicle hulls
• Feathered edges over larger areas

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.
