Solid performer

Writes well and erases cleanly. I deducted one star simply because I wish it came in a multi-pack, but the quality of the single pen is excellent.

No smudging!

Finally found a marker that dries quickly enough that my son doesn't smear his math problems. Highly recommend for elementary students.

Perfect for my daughter's homework

The fine tip is exactly what we needed for small whiteboard exercises. The ink flows smoothly and erases completely without leaving ghost marks.

Great for travel whiteboards

Compact size fits perfectly in my pencil case. The water-based formula doesn't have a strong chemical smell, which is great for indoor use.

Clean and crisp lines

I use this for planning my weekly schedule on a glass board. The 1.0mm tip gives very professional-looking results and wipes off easily with a dry cloth.

Good value, nice size

Bought these for our classroom. The small head allows for detailed writing. Only minor issue is the cap can be a bit tight for younger kids to open alone.

5 FAQ

Q: Is the black ink opaque enough for colored boards?

A: The black ink provides good contrast on standard white or light-colored glass boards. It is not recommended for use on dark-colored surfaces as visibility will be low.

Q: Can this be used on regular paper?

A: While it can write on paper, it is specifically designed for non-porous surfaces like whiteboards and glass. On paper, the ink may bleed through or take longer to dry compared to standard pens.

Q: Is this marker safe for children to use unsupervised?

A: Yes, the ink is water-based and non-toxic, making it safe for children. However, as with any stationery item, adult supervision is recommended for very young children.

Q: How long does the ink last with daily use?

A: With average daily use for writing and erasing, one marker typically lasts several weeks. Lifespan depends on the surface area covered per day.

Q: Does it come with an eraser attached?

A: No, this specific model (K0603) does not have a built-in eraser on the cap. You will need to use a separate whiteboard eraser or a soft cloth.
