Artline 5109A Magnum White Board Markers Dry Erase with Jumbo Big Nib For Clear, Visible Lettering, Black, Red, Blue, and Green - 4 Pack

These are really great super thick dry erase pens. And they are cost effective because they are refillable! However many people don’t read instructions (to be honest most of us wouldn’t think we needed to for markers lol) and so some may think they received a defective product. They did not receive a defective product. They simply opened the marker improperly.The cap has two configurations: one for uncapping and writing - and the other for opening the marker to refill the ink.To use the marker for writing one must simply pull off the cap. (*Do not unscrew it!) It’s not super easy to pull the cap off. That’s a good thing. You do not want the marker to dry out or leak ink.(*If you unscrew the cap, you will be opening up the refillable inkwell to the marker, and on the underside of the marker you will find the wick that supplies the marker for writing. Take note, that is not a “defective” marker that has been assembled improperly. Screw the lid back on tightly and now pull the lid off instead to be able to write with the marker.)In short: These are really great markers! And super cost effective because they are meant to be refillable - so able to be kept and used far longer than most other brands (a concept that seems to be lost on many in our “use it once and throw it away” society of late apparently). Even if you never refill them they are a great product at a great price. But isn’t it nice to know you’ll have the option to decide if you want to throw them into a landfill someday OR instead take a few mins to learn how to refill them?

These large wedge tip markers are great when teaching a large classes as I often do. The red ones don’t erase very well, and they don’t smell weird enough to make me feel like I’m getting high by the end of class.

I don't know how long these last yet, but I've been very happy with how easy they are to see from the back of the classroom! They're huge, like poster markers. I recommended them to all my colleagues! I can't wait to see how well they work after refilling them, but hopefully, it will be a while before I have to do that!

The color is nice and dark but not much thicker than other dry erase markers. The top is difficult to get off, difficult enough that I hesitate to use them.

I struggle to find dry erase markers thick enough to be seen in a lecture hall. These do the trick. The only negative is people in my office keep stealing them! So I ordered another set and keep them locked up. Not joking.

These dry markers work great! Larger than the average marker!

Missing the black marker. Only got the other colors but the black one was not in the package but isn’t available for returns/exchange 🤨

Long Lasting
