Good quality
Writes very smoothly. I have found it very difficult to find a good green ink pen. It is a ink pen, not ball point. So if the paper is not of good quality it will spread.

Best pen ever
If you came like me to see the review before buying these pens, this pen is perfect. Just buy it other ways it is a bit costly and the ink is bit light color. This is lightweight and durable. Also waterproof and smudge free on most of surfaces. By the way this is perfect and buy this.

One of the favourite
Great pen. No leakage whatsoever. Doesn't smudge. Lasts long so value for money. Vivid colours Not refillable tho. This is not waterproof but blue, black and red colours are waterproof. Overall a great pen.

Really good
100 times better than pilot pet. Dries quicker, smudges less (although it still doesn't dry as fast as to avoid smudging accidentally), really good ink colour and the best of all - IT DOES NOT BLEED through the page at all!! A lot of these liquid ink pen has horrible bleeding problems that makes them really unusable with standard pages but this one avoids that problems as it has no bleeding problems at all. Definitely recommend it, it's priced decently for its quality too. The only problem I have with this is the build isn't as attractive as the other Uniball pens.
