[Product Description] ``Onishi Seisakusho'' is a writing instrument workshop where craftsmen produce handmade writing instruments from materials such as celluloid, acrylic, and acetate, cutting, carving, lathing, processing, and polishing, all by hand. These warm handmade pens are made one by one with great care and attention to detail using highly honed craftsmanship. Using an old-fashioned tool called a potter's wheel, we carve each piece of square lumber from a material called acetyloid (acetate), a fiber-based resin, and carefully finish it by polishing it.
