Sailor's Rei series showcases traditional urushi lacquer techniques from various regions across Japan. Urushi lacquer is prized for its beautiful finish and also is incredibly durable and naturally antibacterial, leading to its use in art, furniture, dishware, temples, and more since thousands of years ago. The process of creating urushi lacquerware is time-consuming and labor-intensive; it involves the application of dozens of layers of urushi lacquer, each of which must fully dry in a humidity- and temperature-controlled chamber before being polished with charcoal powder and recoated. Consequently, each pen can take months to complete. The result is a smooth, glossy, highly refined finish.
