The Flat Pen Case - comodo now has a new addition: Hello Kitty “Friends with my Techo.”
The name “comodo” comes from a musical term in Italian meaning “easy” or “comfortable,” in hopes that you will be able to use this pen case comfortably with your techo.
A global pop icon and a driving force behind Japan’s “kawaii” culture, Hello Kitty has been loved across generations and borders. Now, Hello Kitty and the Hobonichi Techo have come together for a special collaboration. This design, which matches the Weeks, is based on the “Hello Kitty Classic” design that has been popular since her debut in the 1970s.
Whether she is playfully framing her face with a techo or sitting nicely to read it, the design depicts Kitty playing in special poses created exclusively for the Hobonichi Techo, all rendered through the weave of necktie fabric. Her familiar, adorable silhouettes are intricately woven into a rich variety of patterns. Because it is crafted from genuine necktie fabric, the material offers a pleasant feel and an elegant, silky shine.
The pen case comes with an easily adjustable band designed to attach to Original and Cousin size covers, as well as the covers of Weeks and HON (A5 size) books. The band is made from a durable elastic that won’t easily stretch out, ensuring it stays securely fastened to your techo.
Because you can slip a pen right into the front pocket, it is easy to grab and store your pen while the case is still attached to your book. The interior is a refreshing light blue and features a handy mesh pocket. This makes it easy to see what is inside, perfect for tucking away small items like stickers and sticky notes.
To keep the case as compact and flat as possible, the zipper pull and band are specially designed to minimize bulk. Despite its slim profile, it has enough storage capacity to hold a 15cm ruler, making it the perfect size to carry alongside your techo wherever you go.
Beneath the band is a Tools & Toys tag that adds a decorative accent to the design.
Of course, it is perfect to use alongside the Hello Kitty series, but this pen case also adds a lovely accent to any techo cover, Weeks, or HON you already own.

The Hello Kitty series features a variety of stationery and accessories you can use alongside your techo. See the full Hello Kitty series here.
