Keegan Uhl, who you may recognize as the creator of the Park Sloper wallet + notebook cover, also makes a variety of leather covers specifically designed to fit a Hobonichi Techo planner.

If you happen to be the lucky owner of a Hobonichi, any one of these covers will not only help keep the planner in good condition throughout the year, it will also make the Hobonichi look better than ever. In fact, the leather will only get more beautiful over time — it should be useful for many years to come, as long as future Hobonichi planners remain the same size.

There are a number of colors and leathers to choose from, with prices ranging anywhere from $60 to $100. The $80 model (pictured above) is an especially interesting choice that is totally custom-made to order, with a few add-on options available:

• Add Bookmark: +$10
• Add Pen Loop: +$15
• Add Snap Closure: +$20
