uniball™ Jetstream Prime Twist, Ballpoint Pen

Best ballpoint pen ever invented, especially since I am left handed, the ink never gets on my hand, and the smoothness of the ball to the writing surface is phenomenal

uniball™ JETSTREAM RT, Ballpoint Pen

What a nice set! Fun to get to try all the different items! This had the bes care in packaging of all the items. Please take note from companies like JetPens on how to take care when shipping items like stationary supplies.

My absolute favorite non-refillable pen in the most amazing color. Was thrilled to find this for sale online as I was no longer able to find it in box stores or even online sites like Amazon.
