3M Whiteboard Eraser for Whiteboards, 2-Pack, White/Blue (581-WBE), Rectangular foam Eraser

Absolutely amazing product! Yes, it's definitely the "magic eraser" being manufactured and sold by 3M but it simply amazes me that it cleaned SO WELL. I'm talking permanent pen marks that have been on my board for almost 10 years from that one time someone used a permanent pen for one letter on the board before realizing it was a Sharpie, not an expo. Since then, we've been doing our best to use that portion of the board to write the items that purposely utilize that one letter! In one foul swoop, this eraser came and not only wiped that letter off, it cleaned all the streaks from previous erasers and even cleared those shadow letters left behind from darker pens. I definitely recommend this product. I don't know how long it will last because I know those magic erasers don't last very long in and of itself.

I am an educator and have used numerous things to erase whiteboards, some work better than others. But these erasers are the bomb! They completely erase my dry-erase marks without leaving stains or scratching my boards! Such an amazing product for a reasonable price!!!

These are great. They are like magic erasers for a dry erase board. They take off the marker when a regular eraser won't, and are great for the "deep clean" type of an erase. The negatives are that sometimes you need to put a bit of water on it to make it work the best, so not always convenient to just leave on the dry erase board. Also, the color from the marker will stay on this eraser, and dye the white part. Even with the downfalls, it works great and saves the dry erase board well. I use them on my "dry-erase notebook," my notebook that has dry erase pages in it, and it works great.

This is a wonderful eraser with great quality! As an educator who uses a whiteboard often, I was frustrated with my regular Expo eraser leaving marker lines. I thought I needed chemicals to remove them, but this 3M eraser works perfectly—no more marker lines. I highly recommend it!

These whiteboard erasers are FABULOUS. I had an old whiteboard that had years of stains on it and had been left sitting in storage for several years. I tried everything to clean it and nothing worked. On a whim, when buying some new markers, I saw these whiteboard erasers purporting to clean easily and with just water. I honestly couldn't imagine that they would actually work, but I decided to give it a shot because they were so affordable and I needed a new eraser either way...boy am I glad I did! My whiteboard is white again. Completely, utterly, blindingly white. I'm astounded! For my normal day to day use now I just use the eraser dry and it works great. When I first used it I did, in fact, get it wet, and that was able to completely clean my whiteboard of years old stains. I couldn't be more pleased, and I HIGHLY recommend them!

I bought this because I needed a replacement whiteboard eraser. It sucks at that. It very quickly gets saturated with ink dust and becomes useless (it just smears dust all over your board). Also, it will turn your hands the color of the marker, because it's very hard to hold in a way that keeps your fingers clean. HOWEVER, when it comes to removing old marker, this is magic. The streaks and faint lines that normal erasers will leave behind are easily removed with the 3M eraser. I now use a more traditional eraser for day-to-day erasing, but when I start to see things are left behind by that, I'll grab the 3M and give the board a thorough cleaning back to pure white. I think this product has its use, as long as you know what to expect.

I noticed you want to clean the writing surface with the EXPO Dry Erase/rag first (it creates a nice clean coating), then use the white side of the eraser to erase things. (I.e. you need a clean surface) You could ask then what the point of using the eraser over a rag is. Well, the eraser glides over the surface and erases things super fast/effectively. I constantly write and erase things to memorize a bunch of stuff, and it's been a game changer in the ease of erasing stuff. If it gets too dirty, gently clean it with soap and water (it takes some time, however). My only complaint is that the eraser seems fragile, and you should refrain from directly using it with any cleaning solvents (EXPO Dry Erase).

I was thrilled with these erasers. They do a great job of erasing everything and that's really rare. I've never been satisfied with the effectiveness of a whiteboard eraser before but this one works well. The one I have been using has developed a slight tear in the foam over the past 2-3 months however it still works just as well and I haven't used the second one at all yet so it will be a while before I need to order a new 2-pack. The price is right, too.

Súper útil, el mejor borrador!!

Thought this product would be awesome coming from 3M but frankly in 2 or 3 uses the product is in tatters. Not good for the intended use.

São muito boas chegando até a apagar os quadros brancos mais ressecados, aprovadas definitivamente.

Não é mágica, mas até que apaga razoavelmente bem. Bem melhor que a maioria, que praticamente deixa tudo manchado no quadro branco.

No deja manchas borra muy muy bien. Lo que me da risa es que lo confunden con esponja de lavar trastos.
