Buyer guides

Brush questions, answered without the sales pitch

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.
Synthetic or natural bristle — what is the real difference? — Synthetic filament is consistent, uniform and easy to specify by diameter and taper, which makes repeat orders predictable. Natural hair varies from bundle to bundle but brings absorbency and a natural tip that many painters prefer. The right choice depends on the medium and on how tightly you need the next batch to match the last.
Which nail brush shape do I need — flat, oval, liner or ombré? — Flat brushes build and press the acrylic bead. Oval brushes give a softer edge and are more forgiving for beginners. Liner brushes draw thin, continuous lines. Ombré and fan shapes blend colour gradients. A salon range normally needs at least a flat, an oval and a liner.
Round, flat, filbert, liner, fan, angled — what does each artist brush do? — Round brushes draw lines and fill small areas. Flat brushes lay in blocks of colour and cut hard edges. Filberts blend and soften. Liners draw fine continuous lines. Fans feather texture. Angled brushes cut in to edges and corners.
What is a Kolinsky brush and why does it cost more? — A Kolinsky brush uses tail hair from the Siberian weasel, chosen because the hair tapers naturally and recovers its shape. The hair is scarce, sorted by hand and graded by length, which is why a Kolinsky brush costs more than a synthetic one of the same size.
What is a ferrule, and does the type matter? — The ferrule is the metal band that joins the hair to the handle. A seamless drawn ferrule resists solvent and water better than a crimped one, because there is no joint for liquid to enter. Ferrule material and fit affect how long a brush keeps its shape.
Wood, birch, bamboo, acrylic or metal — which handle material should I specify? — Wood and birch give a traditional feel and take lacquer and print well. Bamboo is light and dimensionally stable. Acrylic takes colour and transparency but can be slippery. Metal is the most durable and is common on nail brushes. The choice is usually driven by feel, weight and how the logo will be applied.
How does private-label brush manufacturing work, step by step? — Private label runs in six steps: you send a reference or drawing, we quote hair, ferrule, handle and packaging, you approve a sample, we produce, then we inspect and ship. Samples normally take 7–10 days; production runs from about 15 days for small quantities.
Why is there a minimum order quantity, and what drives it? — A minimum order exists because setting up a brush line — mixing hair bundles, crimping ferrules, turning handles, printing and packing — carries a fixed cost whatever the quantity. The minimum is the quantity at which that setup cost stops dominating the unit price.
OEM, ODM or private label — which one am I actually asking for? — OEM means you supply the design and the factory builds it. ODM means you choose from designs the factory has already developed and brand them as yours. Private label usually means an existing product with your logo and packaging. The three differ in who owns the design and how much tooling is needed.
What packaging options are available for brush orders? — The common options are a PVC or OPP bag, a cloth zip case, a PU pouch, and a printed colour box. Bags are the cheapest and fastest; a printed box or zip case is what turns a brush into a retail product and normally raises the minimum order.
How is a brush actually made in a factory? — A brush is made in seven stages: hair is sorted and weighed, combed into shape, glued into the ferrule, the ferrule is crimped to the handle, the handle is finished and printed, the head is shaped, and the finished brush is inspected and packed.
Which certifications should a brush order have? — For the EU and UK the usual set is EN71 parts 1, 2 and 3 for toy-related articles, RoHS 2.0 where electrical restrictions apply, and REACH documentation on request. ISO 9001 covers the quality system, not the product. Which certificates you actually need depends on the market and the product use.
How do I order a sample before placing a bulk order? — Send the specification or a reference photo, confirm the hair, ferrule, handle and finish, and approve a sample. Standard sample lead time is 7–10 days. Approve the sample in writing — it becomes the production standard for the bulk order.
How should brushes be cleaned and stored to make them last? — Clean with a mild soap and lukewarm water, work the lather into the base of the hair, rinse, reshape the tip and dry it hanging tip-down. Never stand a brush in water or leave solvent in the hair. Drying tip-down is the single change that most extends brush life.
Which fibre should a makeup brush use — natural, synthetic or a blend? — Synthetic fibre suits liquid and cream products because it does not absorb them and washes clean. Natural hair suits powders because the scales pick up and release pigment. Blends are used to hit a price point or a specific softness.
What are the main calligraphy brush types? — Calligraphy brushes divide by hair stiffness and tip shape: stiff wolf or weasel hair for sharp strokes, soft goat hair for large flowing characters, and blended hair for a middle ground. Tip shape — pointed, rounded or split — decides the line quality more than size does.
Which brushes are used outside art and beauty? — Industrial and technical brushes cover glue application, cleaning, surface finishing, dusting and precision work such as forensic fingerprinting. They are specified by bristle stiffness, chemical resistance and handle material rather than by artistic performance.
How are brush orders shipped, and what do the trade terms mean? — Brush orders usually ship by air express for samples and small runs, and by sea for bulk. FOB, CIF and DDP define who pays freight and who clears customs. The right term depends on whether you have your own freight forwarder and how much of the import process you want to handle.
How do I write a brush specification a factory can quote? — A quotable brush specification lists seven things: brush type and use, hair type and length, ferrule material and diameter, handle material and shape, overall length, logo method, and packaging. Missing any one of them turns a quote into a conversation.
