Uni-ball Jetstream Sport rollerball (also known as the Junior). Jetstream hybrid ink writes super-smoothly and dries super-fast. Very popular with left-handed writers. As usual with Uni the ink is waterproof, fade-proof pigment ink - technically superior to most of the competition. Retractable nib and rubber comfort grip.

1.0mm ball writes a 0.45mm line. Set of 3 pens.
