PENCIL LEAD AND PENCIL ROTRING PEN GAME

rOtring trio-pen, NOS. A high-quality multifunction writing instrument oriented toward technical drawing, design, or writing is offered at auction.
Unlike other standard multifunction pens that combine colored inks or a single pencil, this model stands out by integrating three different pencils into one body ("3 Feinminenstifte in einem Halter / 3 pencils in one", as indicated on the side of the box).

Color and Finish: The main body has a very elegant matte black finish, characteristic of the brand rOtring's technical designs.
Grip Zone: It features a metallic grip section with a knurled texture (a rough engraving) in black, designed to provide a firm hold and prevent fingers from slipping during precision strokes.
Distinctive Detail: At the top of the body, just before the plunger mechanism, the iconic red ring (rOtring) stands out, the brand's global emblem.
Clip: Includes a very sturdy chrome-plated metal clip to attach to pockets or folders.

The Three Lead Thicknesses
The device is designed to house three of the most standardized and commonly used lead thicknesses in technical and line drawing:
0.3 mm: For extremely fine lines, minute details, or preliminary guides.
0.5 mm: The versatile standard thickness, ideal for both writing and mid-weight lines.
0.7 mm: For thicker lines, contours, or quick shading.
## Operation (Gravity Selection Mechanism)
According to the illustrated instructions on the back of the box, the system works with a pendulum or gravity mechanism:
Selection: At the top end of the pen body, the thickness marks (0.3, 0.5, 0.7) are printed. To activate a specific thickness, you must rotate the pencil lead so that the desired number points upward (toward you) and then press the top plunger.
Retraction: To store the lead or change thickness, press a small quick-release button (usually located next to the clip) or actuate the mechanism so the tip retracts safely back into the body.
Reload: The illustration also shows that the textured front cone can be unscrewed to access the internal tubes and reload the corresponding leads.
It is a highly valued German engineering tool for its practicality, as it allows changing line thickness instantly without releasing the tool or carrying three separate pencils.

ROTRING PEN:

ROtring 600 ballpoint pen. NOS
This model is a classic of technical and industrial design, widely recognized for its durability, precision, and minimalist Bauhaus-style aesthetics.
Hexagonal Body: The main body of the pen has a six-sided hexagonal shape, fully metal, with a satin matte black finish. This geometry not only gives a modern look but also effectively prevents the pen from rolling and falling when placed on inclined tables or drawing boards.
Knurled Grip Zone: The lower section (where the fingers rest while writing) features a knurled (anti-slip) pattern cut precisely into the metal. It offers a rough texture that guarantees a firm grip and excellent control, reducing fatigue during long writing sessions.
Click Mechanism: It features a metal top button that activates and retracts the tip smoothly and precisely with a press.
Clips: It has a curved and sturdy metal clip, engraved with the rOtring brand, ideal for securely attaching to shirt pockets, notebooks, or cases.

Brand and Color Details
Logo and Inscription: On one of the flat faces of the body, a vertical imprint in the brand's characteristic bright red dictates: rOtring 600.
Distinctive Red Ring: At the top, just below the plunger, it incorporates the emblematic glossy red plastic ring, the universal identity mark of all the brand's premium products.
Lead Type Indicator: Just above the red ring, the knurled upper piece features a small window showing a blue background. In these technical instruments, this area typically serves as an adjustable indicator to recall at a glance the type of ink, color, or thickness of the refill installed.
Dimensions: 13.8 cm long, 7.9 mm wide, weight 26 grams.
