Great value, vibrant colors

The colors are very bright and visible from the back of the room. I deducted one star because the green ink dries out slightly faster than the black, but overall excellent quality.

Refill system works smoothly

Initially skeptical about refilling markers, but this system is foolproof. No mess, no leaks. Definitely buying the bulk refill pack next time.

Good markers, caps could be tighter

The ink flow is fantastic and the capacity is huge. However, if you forget to click the cap on tightly, they do dry out quicker than expected. Just be mindful.

Best purchase for our office conference room

We go through markers quickly in our daily stand-ups. These last weeks longer than the cheap brands. The low odor is also a nice bonus for small rooms.

No more ghosting!

I was tired of wiping my board three times to get old ink off. These erase cleanly every time. The thick tip is perfect for writing large headings.

Perfect for my high school classroom

These markers are a game changer. The direct liquid flow means I don't have to press hard, and the ink lasts much longer than standard markers. The refills are easy to install too.
