Randomly crusing for notebooks and office supplies this morning on amazon and I stumbled across this thing: a 6-ring loose leaf binder mechanism bolted into the familiar Traveler's Notebook-style leather exterior. If you're a Franklin, Dayrunner, or Filofax fanatic, this might be a nice way to move into the TN universe. About US$30.00. Presented for your information only, I have no experience with either the product or the seller. https://www.amazon.com/b-still-Genuine-Notebook-Refillable-Handmade/dp/B01BMZZW36/ref=sr_1_1?ie=UTF8&qid=1488042685&sr=8-1&keywords=b.still+leather+journal
