About these items

🎨 This signature pen writes like a fountain pen with a pen sharpener. The ink is large and does not dry quickly, suitable for fast writing, practicing calligraphy, writing essays, drawing, outlining, drafting, signing, etc., not very suitable for large exams. Writing English is very nice.

🎨 The ink tank inside the pen stores a large amount of ink, and is equipped with a front-end adjustment system to make the ink output more stable and even.

🎨 Unlike conventional rollerballs, the revolutionary nib of the Air 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.

🎨 Equipped with Mitsubishi's new black technology pen tip, you can freely control the thickness of the lines and write briskly and smoothly. 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 people use to modify documents fraudulently.
