Excellent for professional use
As a graphic designer, I go through a lot of ink. This bulk box is cost-effective and the quality matches major brands. The quick-drying feature saves me time on tight deadlines.

Revived my favorite pens
I was about to throw away my dried-out advertising markers, but these refills brought them back to life. The universal fit is accurate, and the color selection is very useful.

Good quality, slight odor
The ink flows smoothly and is truly waterproof once dry. There is a slight chemical smell typical of oil-based inks, but it dissipates quickly. Works well with generic brands too.

Great colors, careful with caps
The pigment density is impressive. Just make sure to cap the bottles tightly after use as the oil base can thicken if left open. Overall, a solid purchase for artists.

Best refill ink I've tried
No clogging issues and the flow is consistent. I used these on glass and plastic surfaces, and the waterproof claim holds up perfectly. Highly recommended for DIY enthusiasts.

Perfect for my poster projects
These refills are exactly what I needed for my old markers. The colors are vibrant, and the oil-based formula dries quickly without smudging. Great value for a 12-color set.
Q: Is this ink safe for use on children's school projects?
A: The ink is non-toxic when dry, but because it is oil-based and requires ventilation during application due to fumes, we recommend adult supervision for younger children.
Q: Can I mix these colors to create custom shades?
A: Yes, since all 12 colors in this set share the same oil-based formulation, they can be safely mixed to create custom shades without separating or clumping.
Q: What is the shelf life of the ink once the bottle is opened?
A: If stored properly with the cap tightly sealed in a cool, dry place, the ink typically remains usable for 12 to 18 months after opening.
Q: How long does it take for the ink to dry on non-porous surfaces?
A: On non-porous surfaces like glass or plastic, the quick-drying formula usually sets within 30 to 60 seconds, though full curing for maximum water resistance may take a few minutes.
Q: Are these refills compatible with Posca paint markers?
A: While they are oil-based and work with many poster pens, Posca markers typically use water-based acrylic ink. Mixing ink types may affect performance, so we recommend testing on a small area first or using water-based refills for Posca.
