Artline 5100A Big Nib Magnum Whiteboard Dry Erase Markers, Extra Thick 5.0mm Bullet Tip, Readable from a Great Distance, Low Odor Colored Markers for School, Black, Red, Blue, Green, 4-Pack

I use these for work on cardboard, and ive noticed three semi important things: 1. These have lasted me longer than sharpie brand/others - I have tried sharpie and other branded markers and these have outlasted all.. 2. You can use these on cardboard and the color payoff is amazing!! It's the strangest thing, but i suppose they put more ink in these for white board uses so the tips do not dry out as quickly as a regular sharpie would. Im never going back. I havent had any issues with it being too wet or smearing after use. But again i only used on cardboard which is very porous - absorbs quickly 3. It is VERY hard to find jumbo permanent marker with a ROUND/BULLET TIP online. i ordered these merely for the tip, as they make writing more efficient; you arent needing to pay attention to the tip direction every time you pop off the cap. I work in a fast pace environment and those chisel tip markers were annoying. Sometimes you would get a fat word out and then a shrimpy word will squiggle out the next time. No more!!

Medium to heavy line/vivid colors.

Absolutely the best, brightest, most comfortable eraseable markers. Do not go for the cheap crap... you get what you pay for.

Works great, ink has good coverage, can be seen from a distance. Successfully used to chirp at THE OSU hockey team as they lost to Michigan. Insults delivered with style, clearly visible from across the ice.

Order these as an inexpensive 4-pack with large reservoirs that should last a while. Don't order them expecting thick lines. Good markers with a large reservoir. Build quality is solid, and they're individually shrink-wrapped to guard against moisture loss before use. Colors are bold, there's almost no odor, and they erase cleanly. The only issue is that these are round tipped (like an art marker), not chisel tipped (like most other whiteboard markers). That means that, although the initial width of the tip is large, by the time you get to the actual writing part of it, it's NO BIGGER than any other regular size marker. Seriously - the lines these put down are exactly the same thickness as my normal everyday chisel tip whiteboard markers.

Best dry erase markers that I’ve ever used.

Great quality

Really nice to write large with they worked better then using the nib end ones.

These whiteboard marker pens were bought as a Christmas gift for my son and they’ve been a big hit. He specifically wanted them for doing algebra on his whiteboard and he absolutely loves them. The colours are clear and easy to see, they write smoothly, and wipe off cleanly without leaving marks behind. They’ve made practicing maths much more enjoyable for him and he uses them all the time. Overall, a great set of markers and a really useful gift. I’m very happy with the quality and would happily buy them again.

Love these for my classroom. Only downside is I have to watch my colleagues very carefully as they keep trying to steal them! Clear and visible even from the back of the class. After decades of teaching I have finally found the perfect whiteboard pen!

Perfect, if it's what you need. Write clearly and rub off easily.

I'm a supply teachers and these pens are wonderful because they write on all whiteboards really clearly. Sometimes you're left a pen and sometimes you aren't. Sometimes all pens are clear on the whiteboard, sometimes the whiteboard is clearly 20+ years old and nothing else works but this. Great everywhere.
