Suitable for presenting as a personalized gift with engraving, and for everyday use. It helps me a lot at work and in the classes that I attend and lead myself. I switched from pens to an automatic pencil a long time ago, since I am a visual and often sketch everything. I only sign official documents with pens. I will take the pen in the same style and case. Different pros: Excellent ergonomic material and clarity in the lines. Balanced and elegant. It is possible to adjust the eraser, it just struck me how well thought out everything is. Durable and reliable. It lies perfectly in the hand and does not slip, does not become greasy and slippery. Writes in any weather and from any angle. Has some cons: The internal mechanism is plastic, looks like a prosthesis on a healthy body.
