Size 4 of the MAESTRO Series 1301 is the mid-size flat in Tobolsky Kolinsky sable: 10.0 mm of hair in a 4.5 mm width. It is the tool for surfaces that are already too big for a round brush – a cloak, a wing, a horse's flank, a vehicle panel or the whole armour of a 54 mm or 75 mm figure.
Compared with size 2 it has a millimetre more hair and almost twice the width. It carries more thinned paint, and one stroke covers a band that would take three with the small brush. With glazes and wet blending that is what matters: fewer strokes mean fewer edges for a drying layer to leave behind.

Size 2 (2.7 mm) is for 28–32 mm figures and detail on flat surfaces. Size 4 is for areas where the small brush would need many strokes side by side. If you paint mostly infantry, start with the 2; if you paint vehicles, monsters or larger scales, the 4 does more of the work.
For busts and very large surfaces there is size 6. If you need a soft transition with no edge at the end of the stroke, reach for the NOVA 1375 size 2 filbert – it is synthetic, cheaper, and its rounded tip leaves no hard edge.
What scales is size 4 for?
On 28 mm figures only for larger areas such as cloaks, wings and bases. It comes into its own on 54 mm and 75 mm figures, monsters, vehicles and smaller-scale busts.
Can I drybrush with it?
No, and we advise against it. Dry scrubbing over edges destroys sable hair and the brush loses its straight edge. Use the synthetic DRY BRUSH 140 for that.
How is it different from a synthetic flat?
Synthetic fibre is stiffer and cheaper, but releases paint less evenly – with a glaze that tends to show as stripes. Sable is softer, holds more paint and gives a smoother stroke. Use synthetic for metallics, washes and texture pastes, sable for paint that has to look good.
How do I keep the edge straight?
After painting, wash it in lukewarm water with 4033 brush soap, draw the hair into a straight edge between your fingers and dry it flat or hair up. Never leave it standing in the water pot – the hair bends and the edge splits.
