Authentic quality

Verified authentic product. Packaging was secure, and all 24 pens were in perfect condition. The ink flow is superior to other brands I've tried in this price range.

Good for students

Bought these for my daughter's design class. She loves the fine tips for detailing. The only downside is that the lighter colors show up less on darker paper, but that's expected.

Smooth writing experience

No scratching or skipping. The grip is comfortable even during long drawing sessions. The metal clip feels sturdy and keeps the cap secure in my pencil case.

Great value for the price

Solid set of pens. The colors are vibrant and the lines are crisp. One pen arrived slightly dry, but after capping it tightly overnight, it worked perfectly. Good purchase overall.

Perfect for architectural sketching

The 0.3mm tip is incredibly consistent. I use these for my architecture finals and the water-soluble feature allows me to add subtle washes without bleeding. Highly recommended for technical drawing.

Love the watercolor effect

As an art major, I needed pens that could double as watercolors. These dissolve beautifully when touched with a wet brush. The 24-color range gives me enough variety for detailed illustrations.

5 FAQ

Q: Is the ink archival or fade-resistant?

A: The ink is high-quality and vibrant, but because it is water-soluble by design for artistic effects, it is not fully waterproof or archival unless fixed with a spray sealant.

Q: Are these pens refillable?

A: No, the FINECOLOUR EF300 series is designed as a disposable set. Once the ink runs out, the entire pen is replaced.

Q: What is the difference between Set A and Set B?

A: Set A and Set B together make up the full 24-color collection. They are usually sold as a combined pack to offer the complete spectrum of colors available in the EF300 line.

Q: Do these come with a carrying case?

A: Yes, the official authentic set typically includes a durable plastic storage case to keep all 24 pens organized and protected.

Q: Can I use these on glossy photo paper?

A: While they can write on glossy surfaces, the water-soluble ink may take longer to dry and could smear if not handled carefully. We recommend testing on a scrap piece first.
