Once I opened it up, I realised that she probably hadn't opened it since working there. Inside, I found some small components that I don't think I've seen before (some sort of terminals, maybe?), some wires with different connectors soldered to their ends, a board of resistors, and an example of cable lacing. I assume all of these things were tests that she had to complete before getting the job.
Anyhow, I just thought I'd share. Any info on the components would be appreciated.
