Kolinsky sable or squirrel hair — which should I choose?
Kolinsky holds its shape and snaps back, so it suits acrylic nail work and precise detail. Squirrel is softer and holds more liquid, which suits watercolour washes and large fills. Choose Kolinsky where control and a sharp point matter; choose squirrel where softness and colour load matter.
What "Kolinsky" actually is
Kolinsky is the tail hair of the Siberian weasel, sold in the brush trade under the name Kolinsky sable even though it is not sable. The hair tapers to a fine natural tip and has high resilience, which is why a Kolinsky brush forms a sharp point and returns to that point after each stroke. For acrylic nail application, that recovery is the property that matters: the brush must pick up a bead, place it, and come back to shape without splaying.
What squirrel hair does differently
Squirrel hair is finer and softer, with a higher capacity for holding liquid and a gentler release. It is the traditional choice for watercolour washes, glazing and large-area colour where a stiff snap would leave marks. The trade-off is control at the tip: a squirrel brush is harder to keep pointed for fine line work.
How to decide
If the job is nail acrylic, gel or fine nail art, Kolinsky is usually the right call. If the job is watercolour, ink washes or soft blending, squirrel gives a smoother release. For mixed ranges, many buyers stock both: a Kolinsky core line plus a squirrel option for the softer end. We manufacture both, and both can carry your own handle, ferrule, colour and logo.
Common questions
Is Kolinsky hair real sable?
No. Kolinsky is Siberian weasel tail hair. "Kolinsky sable" is a trade name for the hair type, not a claim that the hair comes from a sable.
Can squirrel hair be used for nail brushes?
It can, but it is soft for acrylic work. Most nail buyers specify Kolinsky or a synthetic with high resilience instead.
