Mitsubishi JetStream 0.5mm Oil Ballpoint Pen

Mitsubishi JetStream 0.5mm Oil Ballpoint Pen - SXN150075P

Ultra low friction Jet Stream 0.5mm black, 5 pieces, with an addictive smooth writing feel.

The world's first revolutionary ink provides an addictive smooth writing experience with low writing resistance. The ink dries quickly, reducing the stress of getting your hands dirty.

The twin ball mechanism also prevents ink from flowing backwards, and it has a built-in spring tip to prevent ink from leaking from the pen tip. 

Mitsubishi Pencil Uni JetStream has been researched to be smooth like a rollerball point pen and prototypes of over 10,000 different inks. After 5 years of trial and error, this product was finally commercialized.

Even if left unused for a while, the ink doesn't seem to become clogged and the writing experience is smooth.
