Here is a pic of some cable ties (you had asked what they are):

You can buy cable ties in any home improvement store (Lowes, Menards, Home Depot, etc., in the USA).

Our only concern is that the luggage not become unzipped, so we also have been using the twist ties that come with garbage bags. Our house junk drawer seems to collect them on it own.

I'm planning on using the cable ties for my luggage also...my only question is...since I can't bring a knife or scissors with me in my carry on, how do you cut it off when you arrive at your destination and need to get into the suitcase?

I dropped my nail clippers into the bottom of one of the outside zippered pockets of my rolling suitcase and didn't cable-tie that one compartment.

Infotrack- thanks for the cable ties site and details.
