Perfect for large classroom boards

These markers are exactly what I needed for my high school science classroom. The 20mm tip covers so much space quickly, making it easy to draw large diagrams that everyone can see from the back of the room.

Love the refillable feature

Finally, a wide-tip marker that doesn't need to be thrown away immediately after the ink runs low. Being able to refill these saves money and reduces plastic waste. Highly recommended!

Amazing for poster making

I use these for creating event posters on white foam boards. The slanted tip allows for both thick bold lines and slightly thinner strokes depending on the angle. Very versatile tool.

Great ink flow, slightly bulky

The ink flows very smoothly and the colors are vibrant. The only downside is that the barrel is quite thick, so if you have smaller hands, it might feel a bit awkward to hold for long periods.

Good but dries out if cap is loose

The marker writes beautifully when fresh, but I noticed it dries out faster than expected if the cap isn't snapped on perfectly tight. Make sure to listen for the click.

Solid performance for the price

Bought a set for our office conference room. They erase cleanly without leaving ghosting marks. The red and black are particularly striking against our standard white board.

5 FAQ

Q: Is the slanted tip durable or does it fray easily?

A: The tip is made from high-density felt designed to resist fraying even under firm pressure. With normal use, it should maintain its shape for months.

Q: Does the 20mm tip work well on small personal whiteboards?

A: While it can be used on small boards, the 20mm tip is designed for large surfaces. You may find it covers too much area for detailed writing on small personal boards.

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

A: With daily heavy use, a single marker typically lasts 2-3 weeks before needing a refill, depending on how much surface area you cover per day.

Q: Are these markers safe to use in a poorly ventilated room?

A: Yes, our GEnvAnA markers are formulated with low-odor, non-toxic ink that is safe for typical indoor classroom and office environments.

Q: Can I buy refill ink separately for these markers?

A: Absolutely! Refill bottles are available in our store under the 'Accessories' section, compatible with all GEnvAnA refillable marker models.
