Is it ok to mail magnets?

[21ccl]

I got this bumper magnet for a car of Kurt Busch and i want to get it signed. Is there anything i need to do to it so i can mail it off?

Pretty sure for "standard" magnets such as refrigerator and bumper magnets, it is not a problem.. I think its when they are strong magnets it's more of a problem, IIRC.
