DRILLOG is a writing instrument brand that focuses on metal dipping pens with a unique structure, based on the theme of “exploration” and “dialogue. The brand name “DRILLOG” is a coined word made by combining the word “DRILL,” which is also a cutting tool and means repetition and training, and “DIALOG,” which means conversation. Like a drill drilling into the ground, we aim to explore the universal appeal and potential of writing instruments and create products that generate rich dialogue.
