well, I guess Ed that I could get my grubby fingers on these also, but on a trip, it might be nice when you often end up rushing to prep the bike before a flight, to have one of these in a nook in a pannier, or in my repair kit bag, kept clean, and be able to just slap it in the front brake as soon as you take the front wheel off. Put some tape on it to stop it falling out and good to go.
I can easily drop one in the mail if you'd like...
