Storing and transporting gadget cords

I've found that, more and more often, I am having to bring with me cords and chargers and headphones (oh my!) for my various electrical gadgets. It's really annoying to have them all bundled at the bottom of my bag, getting tangled and confused and ultimately, the plastic coating getting torn and broken.

So I have a lot of cords.  But I also have quite a lot of spare glasses cases.  So a top tip is to use a glasses case to store the cords in! I can wrap the cords round tidily, place in the case and they are protected and easy to access.
