## Long description

uni mitsubishi pencil Uni‑Ball Paint PX‑21 black oil‑based marker pen is a single black marker designed for durable, opaque marking on a wide range of surfaces. The pen comes in a white barrel with a compact 11 × 11 mm body and measures 133 mm in length. It uses oil‑based, waterproof paint ink that is silicone‑free and intended for applications requiring a permanent, clearly defined black line.
Advantages
The oil‑based formulation provides strong, opaque coverage that adheres to paper, glass, metal, plastic, wood, fabric and stone. Its 1.2 mm nib produces a defined, consistent stroke suitable for writing, marking and decorative work. The silicone‑free ink reduces the risk of contamination on sensitive surfaces, while the marker’s water‑resistant and fade‑resistant properties help maintain legibility and appearance over time.
Suitable for
Writing and labeling on paper and cardboard
Marking on non‑porous surfaces such as glass, metal and plastic
Decorative details on wood, fabric and stone
Art projects, signage and craft work requiring opaque black ink
Key specifications
Ink type: oil‑based paint, black
Nib width: approximately 1.2 mm
Barrel colour: white
Body dimensions: 11 × 11 mm
Overall length: 133 mm
Pack size: single pen
Silicone‑free formulation
Water‑resistant and fade‑resistant ink
How to use
Shake the marker well before use to mix the oil‑based ink. Press the nib gently on a scrap surface to start ink flow if necessary, then write or draw with steady pressure to achieve a uniform line. For marking on smooth or non‑porous surfaces, allow additional drying time to ensure the paint sets; on porous materials, multiple passes may increase opacity. Recap the pen after use to prevent the nib from drying out.
Usage recommendations
Use on clean, dry surfaces for best adhesion. Test the marker on an inconspicuous area when working with sensitive materials or fabrics. Store horizontally or with the cap secured to maintain ink flow and prevent leakage.
