Uni-ball Jetstream Color Ink Series Ballpoint Pen - 0.5 mm - Light Blue Ink

I bought two of these pens in this color (light blue). And one in black and one in red. One of the light blue ones stopped working the same day I bought it. The other one is still working for me. The black one works wonderfully. These pens are probably similar to Uni Jetstream 0.5 pens, in the sense that some unexpectedly stops writing. But if they do work, they are awesome pens.
