Types of Pen Refills
The D1 pen refill is a typical structure found in most multi-function pencils and many compact or expanding pens. Made from material, typically with a hollow end, it steps 67mm in length and approx 2.3mm in diameter.
We D1 refills from Lamy, Schneider, Zebra, Tombow, Faber-Castell as well as others, and due to the huge selection of pen kinds which use them there clearly was your best option of ink tints like the usual black, blue, red and green. Because of the little ink capacity, all the refills listed below are fine point, though you can find medium and also broad ideas also. In addition to ballpoint refills you can find highlighter refills (in actuality a bright ballpoint pen, as typical highlighter guidelines can not be accommodated in this structure), and stylus ideas. When you yourself have a multi-function pen you can easily generally swap some of the features for alternative refills - eg. modification that little-used purple ballpoint to a green refill, an extra-fine black, or an orange highlighter.
Additionally interesting tend to be Platinum Sarabo refills with crossbreed ink. The initial king associated with crossbreed ink pencils, the Uni-ball Jetstream, is also offered as a D1 refill.
For those who have a refill that appears like one of these simple but with a synthetic screw-top, it's often a D1 you want - the screw-top is part associated with the pen, maybe not area of the refill. Pull the material refill from the screw-top!
