Dotting tools and striping brushes: sizes, control, cleaning

A dotting tool is a metal ball on a handle that places a round drop of polish on the nail. A striping brush is a liner brush with long, thin bristles that draws a line of polish. Between them they cover most of what is searched as nail art: polka dots, flowers, leopard spots, French tips, stripes, plaid and the outlines of any shape.

Both tools work with ordinary polish and need no lamp. Polka dots and cheetah print were among Google's most-searched nail trends of 2025, and plaid, tweed and linework are in the autumn 2026 lists, so the two tools earn their place in a home kit (NewBeauty; The Zoe Report). The skill in both is the same: a small amount of polish, a supported hand and a clean tip.

What is a nail dotting tool and which sizes do you need?

A dotting tool is a stylus with a smooth metal ball at one or both ends that transfers a round bead of polish to the nail. Sets come with ball tips from very fine, for details and centres, to large, for bold dots; Manucurist's double-ended tool, as one example, has a 1.4 mm tip at one end and a 2 mm tip at the other (Manucurist; Pure Spa Direct).

Two sizes cover most designs. A fine tip of around 1 mm makes leopard spots, flower centres, constellations and the dots of a micro pattern. A tip of around 2 mm makes classic polka dots, petals and the base of a gradient. Anything larger is easier to paint with the tip of the bottle brush.

The ball has to be smooth and round. A scratched or flattened tip pulls the drop into a tail as it lifts. Cheap sets are fine as long as the tips pass a fingertip test for burrs.

How do you use a dotting tool step by step?

You will need: a dotting tool with two sizes, the polish for the dots, a palette (foil, a plastic lid or a ceramic tile), a base colour already painted and dry, lint-free pads, remover, a small dish, top coat and cuticle oil.

1. Paint the base colour and let it dry until it is no longer tacky, at least 2 to 3 minutes for a thin coat. A dot placed on a wet base sinks and spreads (Manucurist).
2. Put a drop of the dot colour on the palette. Work from that, not from the bottle; polish on a palette thickens slowly and gives a rounder dot.
3. Dip the tip into the edge of the drop so that only the ball is coated. Polish up the shaft runs down and floods the dot.
4. Touch the tip straight down onto the nail, hold for a moment and lift straight up. The longer the tip rests, the larger the dot (Pure Spa Direct). Lifting at an angle drags a tail.
5. Re-dip after every one or two dots. Each dot leaves less polish on the ball, so a row of dots from one dip shrinks; a graded row uses this on purpose.
6. Wipe the tip on a pad damp with remover before changing colour and after every use (Manucurist).
7. Let the dots dry for 3 to 5 minutes, then seal with a thin top coat. Float the top coat on with a light stroke; pressing drags wet dots.

Which dot size gives which design?

Dot size and spacing decide what the eye reads. Five equal dots in a ring with a contrasting centre read as a flower; random black dots of two sizes over a warm base read as leopard; dots that shrink from base to tip read as a gradient (Pure Spa Direct).

A dotted French tip, a row of fine dots along the smile line instead of a solid white, is one of the easiest versions of the trend and needs only the fine tip. The full French method is in French tips at home.

What is a striping brush and how do you control it?

A striping brush, also sold as a liner or striper, is a nail-art brush with a few long, fine bristles that draws straight lines and small details, and it is the tool for plaid, geometric patterns, stripes and animal prints (Maniology). The bristles hold a line of polish along their length and lay it down as the brush is pulled.

Length is control. The longer the brush, the more it evens out any shakiness in the hand, so a long striper draws a straighter line than a short one, even though it looks harder to use (Maniology). Short detail brushes are for curves, tiny shapes and filling.

Load the brush from the palette, drawing it through the drop so the bristles are coated but not clumped. Rest the little finger and the heel of the hand on the table, place the tip at the far end of the line and pull the brush towards you in one steady motion. Pushing a striper away from you splays the bristles. For a line across the nail, turn the finger, not the brush.

How thick should the polish be for dots and stripes?

Fresh crème polish of normal bottle consistency is the right thickness for both tools. Polish that is too thin runs off the ball and bleeds along the line; polish that is too thick makes a domed dot that stays soft for hours and a stripe with ragged edges. Old, thickened polish is the most common cause of bad dots.

Thin a thick polish with a few drops of polish thinner, which replaces the evaporated solvents. Remover is not a thinner: acetone breaks down the film-former and the polish never sets properly again. Advice on bottle care is in how to store nail polish.

Opaque crèmes give the cleanest dots and lines because one touch covers. Sheer, jelly and shimmer polishes show the base through and need a second touch in the same spot. A foil shimmer such as India Anaïs Gilded Hour makes a fine gold line over an amethyst crème; the first edition is sold out and the next edition is planned for spring 2027.

How do you clean dotting tools and nail art brushes?

Dotting tools are cleaned with remover on a pad, immediately. Manucurist's instruction is to clean the end in nail polish remover every time you change colour and after every use; a brief soak in acetone shifts dried build-up, followed by a wipe (Manucurist; Pure Spa Direct). Dried polish on the ball is what turns a round dot into a comma.

Brushes need more care. Swirl the bristles in a small dish of remover or brush cleaner until the polish loosens, wipe them flat on a pad from ferrule to tip, and reshape the point with the fingers. Acetone dissolves the glue in the ferrule over time, so dip the bristles only, never the whole head, and never leave a brush standing in solvent.

Dry brushes flat or tip-down, and store them with a cap over the bristles. A striper whose bristles have bent will not draw a straight line again; a fresh one costs a few euros.

What can you use instead of a dotting tool?

Any smooth round point does the job of the tool for an evening. The rounded end of a bobby pin, the head of a dressmaker's pin pushed into a pencil eraser, the end of a ballpoint pen with the refill removed, and a wooden toothpick all place a dot; the toothpick gives the finest and the pen barrel the largest.

Substitutes place a dot and nothing more. A pin head holds less polish than a ball tip, so it runs dry after one dot, and a toothpick absorbs solvent and softens. For flowers and gradients across ten nails the tool is worth its few euros.

A striping brush has no real substitute. A fine artist's liner brush from an art shop, size 0 or 00 with synthetic bristles, is the same tool under another name and works as well.
