Art and Stationery Supplies Design Serpentinata Pen by KAIRI EGUCHI In a rapidly changing society, the supply of products has reached saturation. The production and sales cycle of "producing more than demand" and "selling cheaply if they are left" methods have remained unchanged for decades, at the expense of the environment.The idea of using new production technologies, to create products that suit one only, which prevent waste caused by mass production is why Serpentinata, a 3D printed pen is born. Serpentinata is designed under the concept and aim of "reducing the impact on the environment by producing only what we need".
