This pen case can attach to your techo with an elastic band to carry your utensils alongside your techo. The name comes from the Italian musical term “comodo,” meaning “easy” or “comfortable,” in hopes that you will be able to use this pen case comfortably with your techo.



The base material is thin yet sturdy. To keep it as compact and as flat as possible, we made sure features such as the zipper pull and band to be as thin as possible. It’s spacious enough to fit a 15cm ruler, but compact enough to easily carry with the techo.



There is a pocket on the front to store pens you use frequently and want to access easily while keeping the case on the techo. There’s a mesh pocket on the inside that’s easy to see what you stored inside where you can keep small items such as stickers and sticky notes.



The back has a band which you can easily adjust its length. You can adjust it to fit the techo you’re using, whether it be an A6 or A5 size cover or Weeks book. The band is made of elastic that does not loosen easily and can be securely fastened to the techo.







It comes in four designs. Black has a black band paired with a navy zipper and interior it’s easy to use in various situations. Gray has a pale gray zipper and band that’s brighter than the surface color and is paired with a pale green interior for a fresh look. Camel has a light blue band that gives it a bright impression. The color combination is easy to use with various techo cover designs. The Liberty Fabrics: Michelle matches the techo cover. The shiny ribbon on the zipper pull makes this even more lovely. The zipper pull and interior is a dull pale blue, and the band is a bright beige.



They all come with a Tools & Toys tag that acts as an accent.



These pen cases allow you to enjoy color and pattern combinations with your techo cover or Weeks book.
