Good but caps can be loose
The writing quality is fantastic and the lines are crisp. However, I noticed that two of the caps in my set were slightly loose, which worries me about the ink drying out over time.

Solid starter set
Bought this for my daughter who is learning to draw comics. She loves the variety of sizes. The case keeps them organized, though I wish it was a bit more durable.

Great value for students
As an art student, I go through pens quickly. This set offers excellent quality at a reasonable price. The waterproof feature is a lifesaver when I add watercolor washes over my ink lines.

Anime artists rejoice!
I use these specifically for inking my manga panels. The 0.05mm and 0.1mm tips are perfect for hair details and hatching. They haven't clogged even after weeks of daily use.

Smooth and consistent
I've tried many brands, and Croma holds up well against more expensive options. The pigment black is deep and opaque. Highly recommend for technical drawing and bullet journaling.

Perfect for my architecture sketches
These fineliners are incredibly precise. The different tip sizes allow me to create varied line weights easily, which is essential for my drafting work. The ink flows smoothly without skipping.
Q: Do these work well on glossy photo paper?
A: While they work best on porous papers like sketch pads or Bristol board, they can write on glossy surfaces. However, the drying time may be longer, and there is a slight risk of smearing if touched too soon.
Q: Is the plastic case sturdy enough for travel?
A: The included plastic case is designed for organization and light protection. For heavy-duty travel or rough handling, we recommend placing the case inside a padded pouch or backpack compartment.
Q: Can I refill these pens when they run out of ink?
A: No, the Croma Micro Fineliner pens are disposable and not designed to be refilled. Once the ink is depleted, the entire pen should be recycled according to local guidelines.
Q: What is the smallest tip size included in this specific set?
A: This 12-piece set includes a 0.05mm tip, which is our finest size, perfect for intricate details in anime eyes or architectural textures.
Q: Are these pens truly waterproof if I paint over them with watercolors?
A: Yes, these pens use pigment-based ink that is designed to be waterproof once dry. You can safely apply watercolor washes over your lines without them bleeding or smudging.
