Hello. This looks neat. Could you please give me the favour of telling me where I would purchase or how to make up the ink that is used on the paper. Or perhaps it is the type of paper that allows this to happen?, I thank you in advance. Have a great day.Mark.

Not positive these are exactly the same, but "Heat erasable pens" (I'm sure it's the ink that's erasable :D) are available on Amazon and quite inexpensive. Used by tailors and such to mark on fabric.
