Colouring Pens Buying Guide: How to Choose the Right Set

Whether for adult colouring, organising a bullet journal, or children's creative activities, finding the right set of colouring pens can be a daunting task. Faced with a jungle of options, it's easy to get lost and end up with buyer's remorse. This guide is here to help you avoid the common pitfalls and identify the criteria that will truly make a difference for your needs.

The 3 Pitfalls to Avoid When Buying Pens

Before we break down the technical specs, let's review the classic disappointments so you don't fall into the trap.

1. Premature drying: Nothing is more frustrating than a pen that dries out after just a few uses. A poorly designed cap or low-quality ink are often the culprits.
2. A tip that wears out quickly: A tip that gets crushed, frays, or retracts makes the pen useless for precise work. Its robustness is an all-too-often overlooked factor for durability.
3. Ink that bleeds through the paper: Some pens, especially alcohol-based ones, have an annoying tendency to bleed through standard paper, ruining the next page of your notebook or colouring book in the process.

Key Criteria for an Informed Choice

To avoid these letdowns, a few technical points deserve your full attention. These are what will determine the quality and suitability of a felt-tip pen for your use.

1. Tip Type: The Key to Your Craft

The shape of the tip determines the type of line you can achieve.

• Fine tip (0.3 mm - 0.7 mm): Ideal for writing, fine details, and bullet journaling. These fine-tip pens offer surgical precision.
• Medium or bullet tip (approx. 1 mm): This is the ultimate all-rounder tip, suitable for both drawing and colouring medium-sized areas. It offers the best balance between coverage and precision.
• Broad or chisel tip: Designed for filling in large areas with solid colour or for lettering (calligraphy), it allows you to vary the line width depending on the angle.
• Dual tip: Increasingly popular, dual-tip pens often combine a fine tip and a broader one (brush or medium), offering the best of both worlds in a single tool.

2. Ink Composition: Water-Based or Alcohol-Based?

This is a decisive criterion: it directly affects the colour rendering and how the pen behaves on paper.

• Water-based ink: This is the most common type. It is generally odourless, doesn't bleed through most papers, and, for some models, is washable. Washable pens are particularly recommended for children. The colours can be layered, but be careful: going over the same spot multiple times can leave marks or even cause the paper to pill.
• Alcohol-based ink: The choice of professional illustrators. It provides perfectly uniform blocks of colour and incredibly smooth gradients. The downside: it has a stronger smell and almost always bleeds through standard paper. Using thick, suitable paper (like layout paper) is therefore essential.

3. Ergonomics and Durability

Certain design details make all the difference in use. An ergonomic shape (triangular, for example) ensures a more comfortable grip. Another point to watch for: "anti-dry-out" technologies that allow the pen to be left uncapped for several hours (or even days for the best ones) without the tip drying out. A significant advantage for absent-minded users or during long creative sessions.

Frequently Asked Questions About Pens

How do I keep my pens from drying out?

The golden rule: always cap the pen tightly after use, until you hear the tell-tale "click". For optimal storage, keep them horizontal: this allows the ink to distribute evenly in the nib. Note that some models, like the STABILO Pen 68, include an anti-dry-out technology that, according to the brand, allows them to stay open for up to 24 hours without drying out.

What's the difference between pens for adults and for children?

Pens for adults generally focus on a richer colour palette, finer tips for complex details, and higher-quality inks for smooth, solid colour application. In contrast, pens for children prioritise safety and practicality: robust and rounded tips, thicker barrels for a good grip, and, an essential criterion, washable ink.

Can you create a watercolour effect with water-based pens?

Yes, many water-based drawing pens are water-soluble. The principle is simple: apply the colour to the paper, then work it with a wet brush to create wash effects and beautiful gradients. For best results, it is highly recommended to use paper suitable for watercolour (thicker and more absorbent) to prevent the sheet from buckling. Models like the STABILO Pen 68 are often praised for this versatility.
