## Long description

uni mitsubishi pencil UM-100 red is a refillable gel rollerball pen engineered for smooth, consistent writing in everyday situations. The pen uses gel ink in a rollerball format that provides fluid ink flow and even coverage. Its medium tip delivers a balanced line width that enhances legibility for note-taking, form filling and routine writing tasks. A refillable design reduces waste and allows long-term use with compatible gel ink refills.
Advantages
The UM-100 offers reliable ink flow and a comfortable medium tip that suits a variety of handwriting styles. The gel ink dries relatively quickly while maintaining good saturation, producing clear red lines without frequent skips. Its refillable mechanism makes it a practical choice for users who prefer a reusable pen body and replacement cartridges. The pen’s rollerball construction provides a consistent feel across different writing speeds and angles.
Suitable for
 Everyday note-taking at school, university or work
 Completing forms and documents that require colored ink
 Annotating printed materials and correcting drafts
 Personal journaling and planning where color distinction is useful
Key specifications
 Ink type: gel ink for smooth, consistent delivery
 Tip size: medium for balanced line width and legibility
 Color: red for high visibility and contrast
 Refillable: compatible with designated gel ink refills for long-term use
 Writing system: rollerball for fluid ink flow
How to use
To start writing, remove the cap or extend the tip as applicable and hold the pen at a comfortable angle. Apply light, steady pressure—gel rollerball pens require less force than ballpoints to maintain ink flow. For best results on standard paper, write in smooth strokes and allow a brief moment for the ink to dry before stacking pages or closing notebooks. When the ink supply is exhausted, replace the cartridge with a compatible refill according to the refill instructions.
Usage recommendations
Store the pen capped or retracted when not in use to prevent the tip from drying. Use paper with moderate absorbency to reduce smudging and choose quality refills from the same brand to maintain consistent ink performance and color tone.
