I tried this pack of CD/DVD markers. They are not great quality. For starters, the green marker was already half-dry and writes in blue, not green. The biggest gripe I have is the dry time. The ink takes forever to fully dry and smudges very easily. This is a big problem if you do a lot of burning and care about the appearance of your discs.I would suggest trying Staedtler's CD-R pens instead. They produce a better mark, they don't smudge so easily and they last forever.
