As a uni student and a kmart employee, pen's have always been important and used on a daily basis. Back when i was younger i use to purchase the el-cheapo pen's thinking that a pen was a pen, however after writing with these, i found that every line i wrote felt stiff, sharp and would consistantly run out of ink.
From that very day, i always bought packs of 15 - 20 Papermate Ball Point pens. These standard blue pens are basic, yet do everything an expensive pen can do at a third of the cost. And for me, at home and at work i didn't care which pen i had, as long as when with people and signing important documents we used our other pens. These papermate pens are smooth and don't feel like your writing with a needle. As well as that, the blue ink is reliable and consistant on a daily basis.
Whats best about these pens is that it's not the end of the world if you lose one. At a cost of barely 15 to 20 cents a pen, i always leave them everywhere, both at work, on my computer desk and in books. This is mainly so i can find a pen everywhere i go, and am not worried about ever losing one.
In the end a pen is simply not a pen. What you need is something thats reliable, cheap and doesn't feel like writing with a needle, and for that go papermate. :)
