mom2... No, as far as I know you are not allowed to send anything at all except books through a vendor and they must be paperback and on the approved list. I believe you can send writing materials also but that would also have to be through a vendor like Rosiegraphics.
Just call the unit and ask and they should be able to help. They were always pretty decent when I would call and ask questions.
Best of luck and let us know if you need anything else!
