BongoTies

When I ran into these, one thing was clear: These ties were the answer to all my cable problems.
These ties look good, they attach very easy to your cable and they aren't in your way when attached to the end of your cable. Easy on, easy of. Due to the elastic band, they cover a great range of diameters.
They come in black and natural coloured versions. I like the black ones best for stage us.
The "Bongo", closure pin, is still visible in low-light circumstances.

Once you have these around, you'll use them for a million of little tasks!

Check out the BongoTies website and see loads of examples of how to use them.
