Organise your wiring with shrink tubes...

I'll be honest, I am no electrician but recently when looking to sort some bits of small wiring out (I never recommend a non-pro does wiring) I found out about the humble shrink tube.

I have seen them lots but never thought about purchasing them but they are exactly what I need for fixing some speaker wires, sorting some striped wires near a plug and a few other small projects.

If you are already an electrician then you obviously know what they are and all there glorious usages. As I am quite a newbie I won't be doing any dangerous jobs but would appreciate finding out what you would recommend using them for?

Thanks for reading....
