the first pen used of this order might been potential for captain of shipment since it started out as a skipper, finding out from research some made that the ink consistency won't flow well because of mixture slightly off from the last of the last batch made; cure is heat i.e. hot water, run refill or barrel under hot water; what I did was set it outdoors in direct sunlight on ledge of deck for 5, 10 minutes; worked, okay now and goes with the flow, no skipping; can't fault JetPens; still liking the Zebra doing these 1.6 size

Loved the 1.6mm but only thing is ink is a little bit sporadic sometimes.

Seems to be pretty much a standard, run-of-the-mill ballpoint at first use.

Excellent ! I need these 1.6mm tips for my Failing eyesight !

Excellent pen, writes super smooth and a great value
