Good value for money

The replaceable cartridge system is very eco-friendly and cost-effective. The pen feels lightweight but sturdy. It takes a little practice to get used to the softness of the tip compared to felt tips.

Perfect for watercolor sketches

The waterproof ink is a game changer. I can paint over my lines with watercolors without the black ink smudging or bleeding. The tip holds its shape well even after extensive use.

Great flow, quick drying

As a left-handed writer, the quick-dry feature is essential. It dries almost instantly, so no more smeared pages. The only reason for 4 stars is that the cartridge runs out slightly faster than expected.

Best brush pen I've owned

The scientific design really shows. The ink is truly waterproof once dry, making it perfect for outdoor sketching where humidity might be an issue. The grip is comfortable for long sessions.

Excellent for calligraphy practice

I bought this for practicing Japanese calligraphy. The brush tip offers great flexibility, allowing for both thick and thin strokes depending on pressure. Highly recommended for beginners and pros alike.

Reliable and consistent

This is my third Pentel brush pen. The consistency in ink flow is unmatched. It doesn't skip, and the gray pigment mentioned in some descriptions isn't present; this one is a deep, rich black as advertised.

5 FAQ

Q: Can I buy refill cartridges separately?

A: Absolutely. Replacement ink cartridges are sold separately under the Pentel brand, specifically designed for this Quick-Dry series.

Q: What is the difference between this and the standard Pocket Brush?

A: This model features a specialized quick-dry and waterproof formula, whereas the standard Pocket Brush uses regular water-based ink that is not waterproof.

Q: Is the ink truly waterproof for use with markers?

A: Yes, once the ink is completely dry, it is waterproof and resistant to most alcohol-based markers, making it ideal for layering.

Q: How do I prevent the tip from fraying?

A: To maintain the tip, always recap the pen immediately after use and store it horizontally or with the tip facing down to keep the ink flowing to the fibers.

Q: Does this pen work well on glossy paper?

A: While it works on various surfaces, quick-dry performance is best on standard or slightly textured paper. On highly glossy paper, drying time may increase slightly.
