Alcohol, yes. That's the secret to erasing them (from non-porous surfaces), by the way. Thing is, the CD pen I saw last night smelled the same.
If I'd gotten a free pen with the CDs, I probably would have just gone ahead and used it too, unless it really sucked. Sharpies have been what I've had right at hand whenver I've burned a CD though.
