Is the ink permanent? Is it good for signing books, for example?

My son Loves them. I'm not sure about the permanence...they do fade out to where it looks like pencil. I would NOT recommend using for a book signing!

I use them in my office work, and for writing music. I have found that even old entries are still editable/erasable. However, the ink does not smear, is not messy. I use these to write in English or Japanese. Yes, you can use anything to write in another language, but in Japanese I am picky about ink control. These pens offer that. Highly recommended. Buy enough for backup, as your friends and family will steal them.

i wrote them on my cellphone once, it works nicely; but the ink is soft and rubbery to the touch. it could be scratched off though.

The labels are not waterproof and will start to come off when wet. I use them for wine bottles and they are passable but I don't think they would hold up as beer or water bottle labels. The running of the ink depends on the type of ink used. Hp and Epson seem to hold up but the label starts to come off when wet. You might want to get custom labels made that are designed to handle getting wet.

The advantage to this pen is that is does bleed when I wet it. It does not bleed through when I apply it. I use it for sketching. It draws a nice neat line. Then I wet a brush and go over the pen lines to shade the drawing. Once this has dried, it is relatively permanent. Only the yellow top Razor Point has this characteristic. The others are meant to make permanent marks. I am usually working on paper that is a little heavier than printer paper and the pen doesn't bleed through on it.

I have written on wet paper and have rubbed it with a wet sponge. The ink stayed and wrote well. The paper gave out before the writing did.

with this product, I would suggest no as the ink can be 'leaky" it's quite moist. it really needs paper in order for it not to bleed. just my thoughts.

No, they're not a permanent marker. They are a nice writing type pen. They would smudge.

I just tried using a dry erase marker on it. It works, and the ink comes off easily. If you have large piece of metal to attach the sheet to, it would do what you want.

You can write on them but they do mark up easy because of being thermal paper. If you happen to drag a fingernail across it then you will get a faint mark. Kind of like receipt paper does. The lables are fairly thick though.

I haven't gotten the paper too damp, but it doesn't bleed any more. The ink should be permanent on most paper unless you are using on something glossy, then it has that wonderful smear affect that gel ink does.

No, they are permanent. I wipe them with a damp cloth so have not had trouble with them rubbing off. The printing is small enough and flush with the surface so that they could easily be covered with a label. Hope this helps.

I've used mine for that and it works okay, but I think that (despite the cost of special paper) the LiveScribe series does notes better. The inkling is better for sketching/drawing as the potential for a vector output is there.

The older answers for this question are no longer correct. I ordered this in February, 2013, and the blue-black ink that is currently available is no longer permanent. (It used to be, back in the day, that Montblanc blue-black was their only permanent ink. That is no longer the case. Permanent choices are royal blue or black only as of today.)

I wouldn't recommend it for that. I think they are great for everyday use and the ink quality is not the main focus.

I think the writing would stay one pretty well. It may depend on the marker you use. The ones I use take elbow-grease and alcohol to come clean, which means the writing is semi-permanent until I rub the daylights out of it.

It is permanent as long as it was sealed properly. However, it is not a perfect tool and I only use it to seal things temporarily. If the bag you are sealing is thin, it might also burn through and tear the bag.

I would think so, the ink is meant to resist higher temperatures, I don't see how that would keep it from fading over time though.
