【Project Background】
In 2019, Lassana achieved its first collaboration with Sailor Fountain Pen, a long-established writing instrument manufacturer founded in Hiroshima, through X (formerly Twitter). This encounter has fostered a warm relationship between the two companies that values “Hiroshima’s manufacturing”.
And in September 2025, Sailor Fountain Pen will release a new scented ink for dipping pens, “Dipton Bottle Ink Dipton Fragrance Ink for Dips.” 94% of employees have obtained Aromatherapy Certification Level 1 Lasana, which has continued to make products with a focus on fragrances, also resonated with this initiative. Through the common theme of “fragrance”, different genres of hair care and writing instruments met again, and a collaboration from Hiroshima was realized. In this project, the “Seaweed Silky Hair Spray” provided during the factory tour in Lasana uses the scent of Sailor Fountain Pen’s new ink for a limited time. We will deliver a “fragrance experience” that resonates with the five senses from Hiroshima.
About Sailor Fountain Pen Co., Ltd.
Founded in 1911 in Kure City, Hiroshima Prefecture, it has since been a pioneer in the writing instrument industry, including fountain pens and the release of the first ballpoint pen produced in Japan. In April 2021, the main store was moved back to Kure, and we continue to manufacture based on the manufacturing philosophy of “creating tools that enhance functional beauty and stir sensibility.”
Since the release of the “Fountain Pen Nib Sticking Pen hocoro” series, the dipping pen boom has arrived. The existence of dipping pens, which allow you to easily enjoy a variety of inks, has become more accessible. This time, the fifth installment, is now available with a fragrance that spreads its scent when the lid is opened. Fragrance ink, which can be enjoyed both visually (ink color) and smell (aroma), fills the writer’s daily life with a fragrance wafting from the bottle and pen tip. Released on Saturday, September 20, 2025.
