Based on YSTUDIO's classic hexagonal design, the double scalene hexagons result in 12 beautiful relief lines. The bright, contrasting color design showcases a variety of everyday combinations, making it a unique accessory. The pen's cap and barrel are made of aluminum, making them concise and practical, perfect for carrying. The pen clip, meanwhile, retains our classic brass element and is molded using a delicate architectural concept that carefully sculpts every small angle and surface. This new design concept from YSTUDIO, a truly exquisite pen series, will provide people with a timeless experience.
