Traveler's Company's classic Traveler's Notebook's structure is simple, so it’s easy to add charms and beads on to the rubber band. You can start using the passport-sized notebook as is, but adding a zipper case or a pen holder can increase its storage capacity. Adding a connecting band can even increase the number of notebook refills inside the notebook. This is a notebook where you can customize it freely, and the longer you use it, the more the taste and texture of the leather deepen, making carrying it around fun. This consists of a simple cow leather cover made in Chiang Mai, Thailand and a refined notebook with Designphil’s original paper made in Japan.
