A synthetic flat for controlled coverage, blocking in, and edge work.
Rosemary’s Series 222 is a synthetic flat in long-handle format, so it sits in the practical workhorse category rather than the premium natural-hair class. Synthetic flats are usually chosen for durability, predictable spring, and resistance to rougher materials, making them useful for acrylic, model, and general hobby painting. Compared with sable flats, the 222 should feel a little firmer and less absorbent, but also more robust and easier to keep clean. That trade-off is useful when the job calls for repeated loading, scrubbing, or coverage on surfaces that are less delicate than watercolour paper. The long handle supports a more extended painting posture, which suits larger miniatures, terrain, and model-making. [inferred]
What makes this brush special
Expect a firmer, more utilitarian feel than a sable flat. The spring should push back quickly, which helps maintain straight edges and keeps the brush from collapsing under pressure. Paint release is likely straightforward rather than buttery, which is often ideal for acrylic work. It should feel dependable more than luxurious. [inferred]

Brush sizes are not standardised across brands — a Size 1 from one maker may differ from another. These brushes are handcrafted, so individual dimensions may vary by 1–2 mm.
How we measure a brushA 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
Wash with lukewarm water and soap after use, especially if used with acrylics that dry quickly in the ferrule. Avoid letting paint creep up into the ferrule area, where it hardens and ruins the flat shape. Store with the bristles protected and reshape the edge while damp. Because this is synthetic, it tolerates frequent cleaning well, but it still should not be left in water or exposed to harsh solvents unnecessarily. [inferred]
