● This time, we expressed the fantastical world of "ANNA SUI" with the original theme of the book project "The Secret Garden." The design incorporates "the story of a secret garden where magical butterflies dance, mischievous cats run through flower fields, and the door opens only at midnight." ● In addition, the "Friction Synergy Knock x ANNA SUI 2-color set" will be released in a limited package with the image of a Christmas coffret. There are three types: "Secret Flower Garden Set," "Magical Butterfly Set," and "Mischievous Cat Set," each with a set of two ink colors combining cool and warm tones. The ballpoint pen has an extra-fine 0.5mm tip, perfect for diaries and memos, and is also recommended as a small Christmas gift. ● 2-color set, set of 3.
