Artis Opus - Series M - Size 1 Brush

Series M is the brush for detail work that's not quite fiddly enough to need the finest tip going. Shorter, stiffer bristles than its Series S sibling mean less flex and more control, while the slightly larger head still holds enough paint to keep a steady line going.

Why it's good

• Kolinsky sable head, size 1 — a step up in capacity from the finest detail sizes
• Shorter bristle length for stiffer, more controlled strokes
• Sits alongside Series S as the stiffer half of the Artis Opus range

Reach for it when a size 0 feels too fine but you still need proper precision — freehand edging, sharp highlights, the fiddly bits that need a firm hand.
