What is your opinion of the quality of this item? The fiber carbon feels light and makes writing a joy. The reason I only gave 3 stars is that you can easily hear and feel the refill moving about in the pen both when writing and when not using the pen. The design is nice but I have numerous other pens and the refill sits better in those than in this one. 5 stars Due to being able to feel the refill moving within the pen is why I gave value 3 stars.
