Set of 18 uni-ball Uni "The Full Black Boc" fineliner pens provides a consistent black line for writing, sketching, technical drawing and detailed illustration. Each pen delivers reliable ink flow and fine tip control, making this compact boxed set suitable for everyday use by students, designers and artists who need precise strokes and uniform color across multiple tools.

The pens are lightweight and balanced for extended use, suitable for both quick notes and more detailed drawing work.

How to use
Remove a pen from the box and place the cap on the back of the body if required for balance. Hold the fineliner at a comfortable angle and apply gentle, consistent pressure to produce thin, continuous lines. For technical drawing, use a ruler or template to guide straight edges; for freehand sketching, vary pressure and stroke speed to achieve different line weights. Replace caps securely after use to prevent the tips from drying out.
Usage recommendations
Store pens horizontally or upright with caps on, away from direct sunlight and extreme temperatures. Use on suitable paper designed for ink to avoid bleed-through and feathering; test on a corner if unsure. Keep several pens from the set available to maintain consistent line quality during longer projects.
