Review on Kentaur Multi Color Pen (Black) 5 In 1 Multi Function Pen With Black, Blue, Red, Green Ballpoint Pen And 0.7Mm Mechanical Pencil (FI-5051) - Uses D1 Refills by Kristen Davis

The pen writes smooth in all colors. I did purchase refills, and have had no problem with them. My only issue with the pen, is not the pen, but the pencil. The cartridge itself is small, so not much lead can fit into it, and is a slight pain to change. However, the pencil spring broke on my pen. I opted to just remove it, and I no longer have the issue. I like the pen enough still, to have bought a second of the exact same model. The pencil spring on the second model feels week, but I simply do not use to the pencil on it, so it hasn't worn out or broken yet. I wish this pen existed, without the pencil and 1 additional color pen.
