The Uni-ball One Gel pen features a simple but elegant design. The firm rubber grip feels really nice and comfortable to hold with. The unique spring-loaded paper clip shape pen clip looks cute and interesting. However, apart from all those distinctive features, there is another most outstanding one which you just won’t miss out, the ink. This pen features a special gel ink with large pigment particle, which means the ink will more likely to stay on the surface of the paper instead of blending through. This makes the colour of the ink looks brighter and more colourful on the paper. It also helps preventing smudges. It is also a fast-drying ink. Your writing will always look clear and crispy!
