This time, under the theme of "Beyond writing as you wish," the next-generation model of the erasable ballpoint pen "Frixion" series, "Frixion Ball Knock Zone," is adorned with "unique art" that allows you to write "darkly and for a long time." Heralbony Co., Ltd. is a company that contracts with artists, mainly those with intellectual disabilities, for art licenses, and develops the "unique art" created by the artists into various businesses, including artwork, collaborative products, and events. Under our group purpose of "Connecting people and creativity," we have supported people's free creative power through the creation of writing instruments. This time, through the collaboration of this "unique art" and writing instruments, we will deliver new value to society through art and writing instruments. The products feature designs of the works of six artists contracted with Heralbony: Satoru Kobayashi, Sanae Sasaki, Marina, Sato, Kadoru Iga, and Ryo Nakao. Among them, Satoru Kobayashi's work "Omou mama ni kaku wo koeru" is a newly drawn work for this collaboration, with the title arranged in uniquely shaped characters. By printing each of the art designs on the pens on the packaging as well, the product is finished to allow you to enjoy the art more as a whole. The ink color is black, and the popular 0.5mm core diameter for fine writing is used. Type...Ballpoint pen Ink...Gel ink Features...Set Other features...Bulk sale Popular model...Frixion Ball
