Economic and efficient

Buying refills instead of new markers saves so much money. This large capacity bottle lasts our team months. The blue and red are particularly bright and easy to read from a distance.

Exactly what I needed

Fast shipping and the product matches the description perfectly. The low odor is great for our small conference room where ventilation isn't the best.

Good flow, needs care when filling

The ink flows very smoothly into the marker felt. Just take your time with the dropper to avoid overfilling. Overall, a solid product for the price point.

Perfect for our classroom!

We go through marker ink quickly in our school, and this 500ml pack is a lifesaver. The colors are vibrant, and it erases cleanly from our whiteboards. The dropper makes refilling easy without spills.

No more ghosting

I was skeptical about refill ink leaving stains, but this water-based formula wipes away completely. The included eraser is a nice bonus touch. Highly recommend for office use.

Great value, minor cap issue

The ink quality is excellent and dries fast as advertised. My only small complaint is that the bottle caps can be a bit tight to open initially, but once open, the product works perfectly.

5 FAQ

Q: How long does the ink last once the bottle is opened?

A: If kept tightly capped and stored in a cool, dry place, the ink remains usable for up to 12 months after opening.

Q: Can this ink be used on glass boards as well as traditional whiteboards?

A: Yes, this water-based formula is safe and effective on both traditional melamine whiteboards and tempered glass boards.

Q: Does the 500ml volume refer to the total for all three colors or per bottle?

A: The 500ml is the total combined volume. The package includes three bottles, each containing approximately 166ml of ink.

Q: Will this work with Expo brand markers?

A: Yes, our refill ink is designed to be compatible with most major brands of dry-erase markers, including Expo, provided the marker body allows for refilling.

Q: Is the dropper reusable for other liquids?

A: While the dropper is durable, we recommend using it exclusively for these ink refills to prevent cross-contamination and clogging.
