French to English Bus/Financial Education / Pedagogy course package

[please read acute accents on first 'e' of second two words... I am on a strange keyboard and can't insert them]

This is a box which participants in a corporate training course are given, containing notes, notebook, and other course material.

It is the first item of a list of what participants receive: "Box: boite cartonnee aimantee".

One of the items in the box is a CD-rom, so I wonder if the box is 'magnetised' as a form of protection? I am just having trouble finding examples of magnetised boxes on the internet...

Thanks in advance.
