Short memos, long stories. Uncertain love songs, ground-breaking contracts. Additional adjustments and precise calculations. With three decimal places and as a rough calculation. You write them down with the right pen. Within the margins or way outside. You draw them with your pen. You tap the table with it, nervously click it and literally bite down on it. Your pen. Made from materials that suit you best. In the colours that suit you best. Combine your writing style with your own style of writing. By choosing the right pen.
