This smart cover features a clear pocket as its star element and is made of soft, lightweight PVC. Its name, “Alettone”—which refers to the part of an aircraft’s wings called an aileron—was inspired by the way the flap of the cover folds neatly over, much like an aileron folds during flight. While the design has a refined and understated color palette that gives it a sense of elegance, the soft PVC material keeps it light and comfortable to carry. The cover opens and closes with a snap button, and its versatile, minimalist style suits any user or setting.









Foil-stamped in gold is a quiet message meant to be savored, “Writing by hand is like sending your mind on a journey.” The gray material used for the flap has a subtle texture reminiscent of leather, adding a warm, tactile quality.









The clear front pocket is perfect for displaying your favorite cards or stickers.
It can also hold tools like sticky notes and rulers, keeping essentials close at hand.









On the inside right, there’s a pocket to hold cards or tickets. The pen hook is designed to hold a pen by its clip. There’s also a flap on the inner left side that can be used as a bookmark—feel free to make the most of it.









The back of the cover features another large pocket—ideal for storing memo pads or anything you want to grab quickly.



Let this light and graceful cover lift your spirits like a pair of wings, as you take the time to enjoy the act of writing by hand.









There’s also an Alettone document case, perfect for carrying a Hobonichi Techo HON, papers, or stationery. We hope you’ll enjoy using it together with the cover.
