Six pens, six widths, and that is the whole argument for this set: a bullet journal runs on hierarchy, and a single pen flattens it. We keep the 08 at 0.50mm for month headers, the 03 at 0.35mm for the body of a daily log, and the 005 at 0.20mm for the tiny labels inside a habit tracker. The same black in all three is what keeps a busy page looking deliberate instead of patchy, and mixing brands to get that range is how spreads end up with four slightly different blacks on one sheet.
The ink is pigment rather than dye, and it is waterproof and fade resistant once dry. That earns its keep under a highlighter: run a Mildliner across a finished heading and the black stays black rather than greying out and smearing. On dot-grid paper the lines stay crisp, with no feathering into the fibres, and a 0.20mm nib is fine enough to label a single 5mm dot space without crowding the row beside it.
The trade-off is ink capacity. These are fineliners, not workhorses, so a 005 doing dense hatching will run dry well before a gel pen would, and leaving one uncapped while you hunt for a ruler is enough to finish the tip. Cap it between steps, store the set flat, and keep the finest sizes for detail rather than for filling in large areas.
What settles it for us is the archival claim, which matters more in a journal than in a sketchbook. A bullet journal is a record you keep, and a line that fades in a box in five years is a line you have lost. A page that will still read in a decade is most of the job done with one small purchase.
Bottom line: If you buy one pen for your journal, we think it should be this one: six widths, one consistent black, and lines that stay put under a highlighter.
