Where can I buy (print material) obliteration markers?
I have seen this type of product before, but can’t find it at my local Staples. It is essentially a permanent marker used to obliterate (i.e., mask) parts of a print document, say, for the purposes of releasing only specific sections of a document, which falls under an NDA, to a third party. I’ve found that regular black markers tend to simply make the theoretically-obliterated text shiny and still legible at an angle, particularly for laser prints. Suggestions for alternative products are welcome!
