This pen case can be used alongside the Hobonichi Techo. Because the pen case includes an elastic band, you can attach it to your Weeks and carry a few of your favorite pens alongside your techo.



This design features “Opanchu Usagi,” a character created by an illustrator and animator KAWAISOUNI! who is especially popular on social media.



On the front side is the pattern of Opanchu Usagi’s face. The Opanchu Usagi in various expressions scattered throughout will give you a cheerful feeling. In the center, the “OPANCHU USAGI” logo is foil-pressed in silver. The transparent design enables you to see not only the pens inside but also the bright yellow color of the back side of the pen case through the pattern, making it look very lively.



The zipper pull has a charm of an Opanchu as a symbol of Opanchu Usagi.



The case also comes with a black elastic band you can pull over your Weeks book to stop it from opening up within your bag. You can also use it on the Weeks Mega.
