What makes this brush special
A long flat usually feels balanced: not as stiff as a bristle, not as soft as sable. The longer hair gives the brush a bit more glide and a cleaner taper when you lift off the surface. That makes the stroke more forgiving and slightly more fluid than a short flat. The result is a brush that can cover, edge, and shape with very little fuss. [inferred]

How we measure a brush
A visual guide to the measurements shown in the size chart above.
These are the same measurements shown in the size chart above. Brush sizes are not standardised across brands, so use these dimensions when comparing brushes within a series or between manufacturers.
- Tuft Length
- The visible length of the brush hairs, measured from the ferrule to the tip.
- Belly Diameter
- The widest point of the brush head. On round brushes, this is the widest part of the belly.
- Total Length
- The full measurement from the tip of the brush to the end of the handle.
How to care for your brush
Clean with lukewarm water and mild soap after painting, especially when using acrylics. Avoid storing it with the head crushed, since long flats rely on a clean profile for good edge work. Do not leave the brush sitting in water, and dry it before storing to prevent ferrule damage. Synthetic long flats are usually easy to maintain, but only if they are rinsed promptly. [inferred]
