Review: Defective Batch - I like the ones I bought from the shop. The ink in most of these dry quickly.
Review: These have been my favorite pens for years! I absolutely love the color of the blue ink it is vibrant and rich and the 0.5mm tip gives the perfect line thickness. They write so smoothly and sometimes the ink almost looks like marker ink instead of regular pen ink which is actually one of the things I love most about them. If you are looking for a pen that stands out and feels great to write with these are it!

## Features

- The revolutionary nib of the Air, unlike conventional rollerballs, is pressure sensitive, meaning that it gives a writing experience and differentiating line width similar to that of a fountain pen.
- The metal ball of the nib is encased in an acetal plastic, rather than the standard metal surround, which allows for a smoother flow of ink around the ball, and an increased flow as further pressure is applied.
- The 0.5mm ball delivers a line width of between 0.28mm and 0.45mm (dependent on pressure).
- Features Uni's high quality "Super Ink", which is not only water and light resistant, but also "Tamper-Resistant", meaning that the ink cannot be washed off using chemicals and solutions used by people to fraudulently modify documents.
- Contains 12 Blue Ink Pen
