@sgtstretch at least, in the volumes order. Not sure if included in a “just the pencils” order.
@camacho yeah, there's usually a little goody along with the pack of 12 pencils and the "archive" pencil.
They do so many different editions that they'll probably be hit and miss as far as how interesting they are to you. Some are awesome to me (like this) and some aren't aligned to my interests at all.
