Uni-ball Jetstream is the pen of your dreams. Jetstream has a slightly more liquid ink than the average ballpoint pen paste, making it an ideal ballpoint pen. It writes quickly and the line is never dashed, and this pen does not need much persuasion (ie tossing on baking paper) to start writing. The body of the button is particularly comfortable to carry, and as a bonus, Jetstream ink dries pleasantly quickly, is water and scatterproof, and is therefore also suitable for time-resistant notes.
The body of the Jetstream is made of plastic and has a rubber surface to hold the fingers to increase grip.
The 0.38mm version makes an ultra-fine line, and the black ink is instantly true black.
