The Schmidt 620, 630, 635, and 6000 are all standard D1 (also known as D or multifunction) ballpoint refills. The 620 is a pressurized refill available in blue ink in a medium line width. The 630 is a standard ballpoint with a plastic color key near the tip. The 630 and the 635 (which doesn’t have the plastic color key) are both available in black, blue, red, or green ink in a medium line width. The 6000 refill uses Schmidt’s easyFLOW system which is similar to the properties of a rollerball refill and can be used on capless pens. This refill is available in blue or black ink in a medium line width. Almost every pen and/or refill maker offers substitutes for these refills.
