DOES NOT EXIST. The best I ever had. With a pentel 0.9 I finished polytechnic in '93. Since then I bought 2 more of the same. The last one was run over by a car. So I tried this one in 0.7. Incredible quality. I don't know about durability but it looks excellent after 3 months.

Whatever you say about this pencil, it's not enough! It is designed for writing and everyday use and it strongly resembles a Pilot fountain pen in its design, like the e95s Pilot, which is the top pen for everyday carry and use!
It is the only mechanical pencil that has a cap to protect its already super durable tip! Don't forget to securely attach the cap for the button to work!
In the luxury category, mechanical pencils are extremely expensive. This one is not only not expensive, but it is also by far the best, at least in terms of performance, writing precision, practicality, comfort, etc.
P.S. 1: The Pentel Ain Stein tips are even better for writing, in 2B hardness, it writes very legible black letters. If you use 0.5mm tips, don't press more than 2 clicks out of the tip if you don't want it to break. In 0.7mm, it can handle 3 clicks comfortably, but I prefer 0.5mm due to its precision (I make slightly more beautiful letters). If you write large letters and apply a lot of pressure when writing, then 0.7mm might be better for you.
2: For writing and everyday carry, the Pentel Graphgear 500 for drawing, and the P205 or Twist Erase III for school, are the best pencils! As known, Pentel pencils are generally the best mechanical pencils in the world. All the Rotring pencils I have just sit and collect dust in the pencil cases unused. Pentel is like Toyota, good and reliable, and Mercedes (Faber Castell) is good, and Porsche is good, but the car you drive constantly is the Toyota! The Kerry, you can call it a Lexus!
