Does sliding these magnets across paper leave a black mark? I hope to use these to display large photos.

I used these to display National Geographic maps, photos printed on a laser printer (using high gloss "photo paper"), and am using some now to display photos on Kodak silver halide. I don't recall ever seeing them leave black tracks, but they're powerful enough that they often leave dimples/impressions in the heavier paper.

I use them on paper and labels, but have not tried them on anything else. They have been terrific for my needs, but think they might not be too successful on other surfaces. Cheers, Sydney

They peeled off my wall without leaving a mark. I was using them for a mural of album covers and they weren't too durable for that purpose but they didn't mess the wall up.

I do not know if they come off easily. I am using them to label my Accelerated Reading books. I am placing a piece of tape over them to make sure the dots do not come off. Sorry I couldn't help you.

Yes, they will. I have been using it for my images with 2 sheets of thick photo paper and the thin sheet between.

I've printed text on them with no problems, just as with any paper labels. There should be no problem with printing cover art on them.

They are pretty strong magnets. I suggest to use sharpies to color instead of the paint they give you, it just makes a mess.

no damage to my paper posters (maps). It clamps on them, so maybe it could crease very delicate paper, but no problem to my fairly thin maps. I don't see it having trouble with the weight of any large poster (though not sure I understand the question).

I never have. I guess it would depend on if they are individual 8.5 x 11 paper. The are many different settings and watermarking features if I recall.

Yes. I use them for family antique photos. I place the photo in the sleeve and usehindge tape to place them in scrap books. Many of the old photos have writing on the back and this way people can flip them over and see the writing without actully toucking the photos.

Antonio, thanks for the question. The magnets are very strong and just in case you are not totally satisfied, write me and I'll take care of you. No worries at all.

I have put these into post bound albums. I haven't had any problems. I think there are some post bound albums that might need specific page protectors but as long as you can use any of the regular 12x12 brands in that album, these will work as well!

I've never used them for that purpose but I can assure you that the magnets are strong. My guess is that you would be pleased.

No, it's like trying to use yellow marker on black paper. I would suggest using something thick, like yellow icing.

I haven't had any issues with them. I use them to print labels for wedding events. I put wedding pictures on them and print them on laser printer.

I have no clue. If they are magnetic surfaces I assume so. Sorry I cannot give you a better answer. I use them as message boards for my newsletters, etc by my desk.

They are not. The cards are metal and the board is magnetic, so they will not stick to other (non-magnetic) surfaces.
