As a highlighter, this product did what it needed to do. None of the ink or
print smudged as I used it. Being advertised as copy-proof, however, I was
disappointed when all the documents I scanned at work using this highlighter
were blacked out in the places where I'd used it. The turquoise is amazing, but
stay away from purple if being copy-proof is a big deal for you.
