This year's Passport Traveler's Notebook underlay is a music themed edition. The underlay is an unobtrusive addition to your Passport Traveler's Notebook which makes it easy to write while you're outside and without access to a flat surface. Also works really well as a 10cm ruler, straight edge and bookmark.
With grid layout on the back (5mm) which can be used as a 10 cm scale or as an underlay.
