Folio: Ocean Blue A5 Cousin Size - Techo Lineup

FolioOcean BlueA5 Cousin Size

2027 New

We have created a techo cover named “Folio,” meaning “folded in two.” It’s a cloth book cover style that slips right onto the Hobonichi Techo book: simply slide the front and back covers of the book into the sleeves, and you’re set. Thin, light, and easy to hold, it’s a design that pursues pure simplicity.

The cover is made from a thick, firm cotton fabric treated with a polyurethane coating. The result is smooth to the touch yet impressively durable.

The left sleeve has one card pocket, and the cover comes with a single bookmark — a minimal setup by design. Rather than a built-in pen holder, the Folio cover comes with a dedicated elastic band. A natural leather patch stamped with “HANDWRITE” holds one thicker pen, while the elastic loop can hold a slimmer one. You won’t have to worry about your techo falling open inside your bag.

The striking blue color evokes the image of the ocean. On the spine, the message “YOU WRITE. YOU DRAW.” is accompanied by an illustration of a sailing ship. Like navigating the voyage of life with your own hands, open your blank techo and let your pen move freely across the page.

Please Read Before You Buy

We’ve compiled a list of warnings, potential issues, and tips to keep in mind for this particular product. Additionally, the color of the product may be slightly different in actuality than compared to how it appeared on a computer or smartphone screen.

Color and print may vary slightly: The cover's color and print pattern are created by dyeing or printing onto white fabric. While we take care to ensure consistency during production, slight variations in color or pattern may occur between individual items. This may also happen across a single cover, such as a pocket compared to the rest of the cover. Minor print blurring or uneven coloring may also be present. In addition, on rare occasions, there may be small black or white dots visible on the print. This is an unavoidable aspect of the manufacturing process.
