I seen this on the nice tight ash blog and I must see they thought of everything, and I can't wait to get one.
It's called Humidor Notes
http://humidornotes.com/
you can write very descriptive info about your smokes and you can glue the band in it if you wish (they include the glue!!!) and it's so small it will fit in your traveldor.
I am not affiliated with this site, just thought I would pass this along.
