This cool blue ballpoint pen is made from recycled marine waste and contact lens cases — so it's a more sustainable way of writing than typical plastic-body pens. Inside the pen is Mitsubishi's highly reliable and popular Uni Jetstream refill. The line width is 0.7 mm and the ink is black. Quick-drying and smooth, the Jetstream ballpoint family has a dedicated following because it works well on all kinds of paper and for all kinds of writing styles. Made in Japan.
