Ask ten miniature painters which brush they swear by and you’ll get a lively debate. At the heart of it is one question: natural Kolinsky sable or synthetic? Both can produce beautiful work, but they behave differently — and the right choice depends on what you paint, how you paint, and your budget. This guide breaks down the real differences so you can choose with confidence.
What is a Kolinsky sable brush?
Kolinsky sable is natural hair prized for one reason above all: each strand tapers to a fine tip and springs back to a sharp point. A good sable brush combines a fine point, a full “belly” that holds a reservoir of paint, and reliable snap (spring). That combination is why sable has been the benchmark for fine art and miniature painting for generations. Our round Kolinsky sable brushes, flats and angled liners are all natural Kolinsky sable for oils, acrylics and enamels.
What are synthetic brushes?
Synthetic brushes use engineered filaments — often “Kolinsky imitation” fibres tuned to mimic the taper and spring of natural hair. Modern synthetics have improved enormously: they hold a respectable point, resist harsh paints and solvents better than natural hair, and cost less. Our Vernissage range is a synthetic Kolinsky-imitation line with good colour absorption and a fine tip, and our gaming & micro brushes use a sable/synthetic blend for hard-wearing everyday detail work.
Sable vs synthetic: the key differences
Point & precision
Top-grade Kolinsky sable still holds the finest, most reliable point — the edge you feel when lining eyes, lace or freehand. Good synthetics come close, but the very best sable is hard to beat for display-level detail.
Paint capacity
Sable’s natural belly carries more thinned paint, so you make fewer trips to the palette and get smoother, more continuous strokes — a real advantage for blending and glazing.
Spring & control
Both can have good snap. Synthetics often feel slightly stiffer, which some painters prefer for control; sable feels softer and more responsive.
Durability
Here synthetics win. They shrug off drybrushing, heavy-bodied paints and the occasional solvent that would wear out natural hair. This is why we make dedicated synthetic dry brushes — you should never drybrush with a good sable.
Cost
Synthetics are more affordable and a smart way to build out a kit or cover rougher jobs. Sable is an investment that, cared for well, lasts for years.
So which should you buy?
Choose Kolinsky sable for detail, blending and display painting — anywhere the finest point and best paint flow matter. Choose synthetic for basecoating, drybrushing, metallics (which are abrasive), and as affordable everyday brushes. Most experienced painters own both: sable for the moments that count, synthetics for the workhorse jobs.
A sensible starter kit: one or two quality sable rounds for detail (a size 0 and a size 1), a synthetic or blend brush for basecoating, and a dry brush for texture. Our round sable sets and Vernissage sets both give you a spread of sizes in one purchase.
Frequently asked questions
Is Kolinsky sable worth the money?
For detail and blending, yes — a good sable holds a finer point and more paint than most synthetics, and cared for properly it lasts for years, making it good value over time.
Are synthetic brushes good enough for beginners?
Absolutely. Synthetics are affordable, forgiving and durable, which makes them ideal while you build skills. Many painters keep using them alongside sable indefinitely.
Can I drybrush with a Kolinsky sable brush?
No — drybrushing is hard on bristles and will ruin a fine sable point. Use a dedicated synthetic dry brush for texture and highlighting.
What brush size should I start with?
A round size 0 or 1 covers most detail work on a 75mm figure, with a larger round or flat for basecoating. A mixed set is the easiest way to get the range.
