SOrry, just one question does it write in pen or pencil or marker or what??
The Xpert accomplishes what the effect description says it accomplishes; no more, no less. But it is NOT a swami (as noted in the effect description), so discussions of what it writes in is irrelevant.
If you'd like to learn more, please do a search, as many answers have been given before. After that, if have any other, non-fishing questions, feel free to drop me a PM.
Thanks for your interest,
