D1 is the short, slim refill used in compact and multi-function pens. In the Kaweco range it is the one for the Sport ball pens — Classic, Skyline, Frosted, AL, AC, Brass and Steel — as well as the Liliput and the Special "S". It will also fit other makers' pens built to the D1 standard.
1.0 mm is the medium width and the standard fit — what most Sport ball pens leave the factory with.
Five refills to a pack. Kaweco's ball pen refills meet the ISO 12757-2 document standard, so they are fit for contracts and anything that needs to still be legible in twenty years.
