Yep, I had a "kit" as well. Stuff that was in mine that isn't in yours:
Switch-cleaner - I used Servisol - cleans jacks, sockets, and switches/pots.
WD40 - people laughed, but it's a water repellent, I used it on bridge saddles as "sweat-protector" for strings (and it worked!)(try and keep it off bare wood, though)
Replacement Plectrums
Replacement guitar leads
Nail scissors and nail file
And you missed gaffa tape because the missus has nicked it for some strange gardening purpose (well, that's what's happened here! :lol:)
