Art and Stationery Supplies Design Creator DIY Modular Ballpoint Pen by DONG GUAN JIAN LIN INDUSTRIAL CO., LTD. Creator is a modular ballpoint pen that users assemble themselves. The hollowed out metal body reveals the screws, springs and mechanical structure inside. External accessories in different colors, shapes and materials connect through a universal interface, so the parts fit together like building blocks and each pen becomes personal. The body is made entirely of metal. Except for refills and springs, most parts are completed in a single process and the materials are fully recyclable, which reduces energy use and material waste.
