How do these work with chalkboard contact paper - do they erase easily?

They are very bright and very liquidy markers so if the material you are using is any at all porous, they're going to be difficult to erase entirely. They wipe clean off glass of course. I would say they would wipe clean off chalkboard paper as well since it is 100% non porous.

I used them on a black standard chalkboard. They look great and super vibrant. Just requires some white board cleaner or windex to get it off.

I honestly do not know, but it MIGHT because of the material they are. Look, you could always try in a corner inconspiculous...but it may stay stained when you try to erase...Hmmmmm. Good luck!

I used a label maker that creates sticker labels. Dry erase would wipe off. Good Luck!

I used them on a chalkboard and could NEVER get it off. Had to paint over it. Maybe try a razor blade and scrape it off. These are permanent in my opinion.

Yep, works great with chalk! Even comes with a piece of white chalk. This has turned out to be one of the best things I've ever purchased for my kids! I love it!

I used mine on a black dry erase board and they worked really well and didn't leave any marks. The colours were also crisp and very visible.

they write very well on chalkboard paint, however they will not remove easily. I have found that you need to paint over with more chalkboard paint if you would like it to remove cleanly.

I have used these on chalkboard paper and on glass and it washes off with water. If you use it on an older, porous chalkboard, it might be harder to get off. I'd suggest trying mild detergent and water.

Frankly, I've used these in other surfaces, but not on regular school boards. I have a chalk board I made in my kids' bedroom's closet door and it worked fine on it. We, however, use a slightly wet cloth to erase which, for purposes of my OCD, helps control any powder flying around the room. This may not be completely helpful information for you, but I can't imagine chalk, liquid or otherwise, not coming off a perfectly normal chalkboard.

I use chalk all different colors. Use damp paper towel to erase, looks new all the time. I like it.

You can use chalk, but the writing fades quickly. These are made to be used with liquid chalk writing pens. Works beautifully with them.

Because there are several chalkboards made by the Threshold brand, I can't say for sure. If the chalkboard is made of a hard plastic or vinyl, then Wonder Chalk will work, but you should always test a small area first. If the surface is porous, meaning that it absorbs, liquid chalk will stain. Slight stains can be removed with a damp white dense sponge eraser, like Magic Eraser or other brands.

They are not permanent is used correctly on a non-porous blackboard (magnetic chalkboard). I write and then erase (using a water/baby wipe or damp sponge, sometimes WEEKS later) and then rewrite all the time for my baby boy's "Monthly Birthday Board". Having said that, I'm not sure if they are permanent if used on a paper surface or on cloth, since that is not their intended use.

I've been using it on the blackboard contact paper. It works fine, but it will smear and rub off with handling. It would be good if it's handled much. It cleans off well.

Hi there...Yes they do...My granddaughter played with it right away and even used sidewalk chalk which wiped away great with eraser, but of course better with a damp rag...Didn't need to "season" the chalkboard either!
