The Sailor 4 Seasons Shiki-Oriori Pro Gear Slim ballpoint comes in 4 gorgeous colors to match the fountain pens that were released in 2015. The Four Seasons Shiki-Oriori Manyou Summer Leaves Metallic Green ballpoint has gold-plated trim and utilizes a twist-action mechanism, with a .7mm refill. The shade of green is inspired by the lush green of grass or foliage in summer, and the deep green barrel and cap have a pearlescent sheen that is utterly gorgeous and unique.
