"My math classroom at a community college has a blackboard in front with a pull-down projector screen. I use the Roll Up sheet in place of the screen, so that I can write on what's being projected.It's a perfect fit, simple to put up and take down because it's magnetic. When class is over I roll it up and take it with me.
My only complaint is that it's a bit pricey. "
I love my whiteboard ; fast delivery; excellent quality...
This is much more convenient when you have to travel to do presentations. Our only issue is that the marker is harder to get off after use.

Marcia Bowie from Concord, CA asked:

Q
Can I attach this to a closet door in my craft room?  Perhaps with strong doublesided adhesive
Answer
Hello Marcia, This probably wouldn't be the ideal product to attach with double-sided tape. If your door is smooth you might be better off with one of our self-adhesive Opti-Rite wallpaper products. Perhaps the magnetic self-adhesive.

Tai from St George, UT asked:

Q
My refrigerator surface has curved edge and some texture on it. Will the sheet attach to it and wrap the curved edge?

I am thinking of using it to cover the whole surface of the refrigerator.  

Answer
Good Day,


I would suggest contacting one of our customer service representatives at 866-366-1500 and request a small sample of the material first. If your refrigerator accepts magnets then there should be no reason why this material would not work. However, the texture of the surface may telegraph through to the writing surface.

Lisa from Jupiter asked:

Q
I have a metal door Do you think it will stay on it?
Answer
Hi Lisa, So long as a normal magnet will stick to the door (meaning, it is magnetic receptive), this product will work.  The magnet is strong are they're applied to porcelain steel whiteboards and metal all of the time.

Answer
Hi Mary, this surface does have a sheen to it.  We have projected onto it, it works, but you will get a reflection.  We also have a peel and stick matte product if it helps:

Patrick from Seattle, WA asked:

Q
I'm interested in using it on a metal door that's 29 1/2 inches wide.  Are there any smaller sizes?  Is it something I could trim with a box knife?
Answer
Hi Patrick! Thanks for the question.

The smallest size we have is 35 1/2 - 45" .
The good news is that these Roll Up Dry Erase Magnet Sheets can definitely be cut or trimmed with a sharp blade or X-Acto Knife. If you're going to use a box cutter, just make sure it's sharp enough! Hope that helped!

Bonnie from CA asked:

Q
Will it adhere to a cement wall?
Answer
Hi Bonnie, no, this is not a peel-n-stick product; it is a magnet sheet that sticks to a fridge/ whiteboard, or any other magnetic surface. If you are looking for a peel-n-stick product we recommend Opti-Rite® here: https://mywhiteboards.com/opti-rite-mag-self-adhesive.html Concrete is a tough one. The self-adhesive backing on Opti-Rite® is only guaranteed to stick to smooth, non-porous surfaces., such as a painted wall or old whiteboard or blackboard. Please call us if you have in depth questions. We are more than happy to chat with you! 866-366-1500.

Answer

Jason Evans from Vermont, USA asked:

Q
Could these be used out doors and hold up to the changeing elements I'm thinking of using this as a menu board and applying it to the outside my food truck that's all metal. Also, could any dry erase marks be used? 
Answer
Hi Jason,

Thank you for your question! You can use the magnet sheet outside, but we don't offer a warranty for that type of use. Temperature changes, rain, and direct sunlight will break down the clear dry-erase surface over time. We would recommend storing the magnet after use. 

If you have any other questions, please call us at 866-366-1500; our team would love to help!

Christy from TN-Tennessee asked:

Q
Do magnetic letters stick to this or is it just to be used as a white board? 
Answer
Hi Christy,

Yes, this sheet is also magnetic receptive. It's not as strong as our magnetic receptive whiteboards, but you should be able to attach lightweight magnetic letters. 

Please let us know if you have any other questions!

Jim from TN, USA asked:

Q
Can this be cut to fit a custom size?
Answer
Hi Marc, thank you for your question. The Mobile Whiteboard Stand has a heavy duty adjustable frame that tightly secures the board in place, as well as a locking mechanism on the wheels to keep from moving. The L brackets accept boards up to 2" thick so as long as your board can be secured within that and is less than 200 lbs, it should be fairly steady when writing on the edges of the board.
