Delineador / Caneta
Pen eyeliners combine reservoir, applicator tip and cap in a slim body, with product travelling to the tip by capillary action. They suit liquid eyeliner, brow pen and retractable pencil. The archive holds 14 options, in small volumes, typically under 5 ml, with tips in several shapes and widths.
The tip defines the line and the audience. A felt tip lays down a firm even line, a brush tip lets thickness vary within a single stroke, a fine tip creates a lash effect. Capillary feed demands controlled viscosity: too thick and it will not travel, too thin and it floods.

How to choose
Start by defining the line the brand wants to deliver, because the tip follows from that. Then validate formula viscosity against the chosen tip, since capillary action only works within a narrow band and this is what most often fails in testing. Check cap sealing as well, because liquid eyeliner dries at the tip and a weak cap ruins the product before it is used up.

Frequently asked questions
What is the difference between a pen eyeliner and a pot with a brush?
A pen carries formula and applicator in one unit, fed automatically by capillary action, which gives convenience and a consistent line. A pot with a brush lets the user control how much product is loaded and generally accepts thicker, more pigmented formulas. The pen wins on convenience, the pot on versatility.
Why does a pen eyeliner skip?
Most often it is a mismatch between formula viscosity and the capillary system. A formula above the working range will not reach the tip and the line breaks up. It also happens when the tip dries out because the cap does not seal well. Both points are testable before the batch.
