Writes beautifully
I love writing with the G-402 Zebra pen. The ink flows seamlessly and writes beautifully. The size is perfect for my small hands and I like that the pen is metal. It makes the pen feel more durable and made of good quality. For the quality, the ink flow, and the fact that you get two, it is worth the price.

Best pen I’ve found
My favorite pens, great weight and the tip is satisfying by to use because of how smooth it writes. High quality steel make up the body, and the chrome color is sleek.

I Love the click.
I love the way these pens write the ink is smooth and dark, and it flows very well. The best part is the clicking mechanism it has a very satisfying feel and sound when you press the button down. The ink does seem to run out fairly quickly, but other than that, it's a fantastic pen for everyday use.

Favorite Pen
Zebra G-402 is my new favorite pen. They have just the right amount of heft without being too heavy. The G-301 looks fine but feels too light and cheap. The G-402 fits right into that sweet spot of being a nice pen that you'd rather not lose, but it won't cost you much to replace. I like the tip shape of the 402, and the rubber grip prevents slipping without being sticky. The ink refills are interchangeable, I've even bought a 2-pack of 301s and cannibalized the ink to put in the 402. The ink lasts a moderate amount of time but I'm not writing essays. The writing experience is very smooth and you can get the refills in 0.5mm or 0.7mm, maybe other sizes too. One word of caution: If you put the pen in a shirt pocket or bag without retracting, IT WILL STAIN whatever fabric it comes into contact with, so be careful. It's not a pen to throw in your pants pocket. But I guess that is the downside of the smooth effortless writing of the cartridge.

Works fine, but a ballpoint pen is probably better.
The pen is ok, I generally would still prefer a sharper ballpoint pen rather than the gel pen.

The perfect pen!
These are the best pens I've ever used. Awesome design, smooth writing, and best value for the price. After using these, I will never use another type of pen. 👍

Metal beats plastic
Smooth writing gel ink. Writes equally as well as Pilot G2. Really like the metal construction and extra heft these offer over the plastic G2 pens.

refill is exact as the one my original's G-402 came with. No complaints and ink flows just as smooth.

Just a great pen, not much else to say. I love the stainless steel look, and the build quality is excellent for the price. It writes smoothly and dries quickly.
