The Papermate Gel is a fairly decent basic retractable gel pen, but there's nothing about it that is getting me particularly excited.
Neatly attired in black and white
To begin with, the barrel is simple in design, with a functional grip and altogether ordinary clip. The bold black and white colour scheme does not particularly appeal to me. I feel that it gives the pen something of a cheap look, but of course your preferences may be different. The plunger mechanism is also completely functional, but again, completely ordinary as well.
But how does it write?
As for writing quality, the Papermate Gel performs fairly well, writing smoothly, but not shockingly so. The ink may dry a bit slowly, but probably no slower than that of similar pens. It reminds me very much of both the Zebra Sarasa and the Pilot G-2, although it feels slightly finer than both of those pens. It is a bit smoother than the G-2 but not quite as smooth as the Sarasa. The Zebra Sarasa is the best of the 0.7mm, retractable gel ink pens that I have used, and I can't think of any reason why someone would choose the Papermate Gel over that pen unless something about the design of the Papermate particularly appealed to them.
The business end
Overall, the Papermate Gel is a decent, functional, and basic retractable gel pen that you couldn't go wrong with. Unfortunately, it is missing that extra something that would make it a pen I would want to buy again.
