Pens themselves look great, feel great to hold, and the printing on them was well done. However- writing with this pen is poor. The tube that holds the ink bends and moves as you write giving a sloppy feel and look to writing.
I myself would like to use my own pens but I'm not inclined to. This is on the cheap end so what can I expect.
It just worries me that customers will also not be inclined to write with the pen. Maybe they would if they had to or if they aren't too picky. At least hopefully they'll grab a pen for free and keep it around somewhere to use occasionally.
