craftinova CR-Ultra-black-30 permanent marker 0.5mm 30 pack

Precision tip for detailed work

These craftinova CR-Ultra-black-30 permanent markers feature a 0.5mm ultra fine point that produces consistent 0.4mm lines for small text, labelling and intricate artwork. The quick-drying, waterproof ink resists fading on paper, glass, metal, plastic, wood and fabric. ASTM D4236 compliant, non-toxic formula makes them suitable for classroom, office and home use. The pack contains 30 black markers.

Check surface and workflow

Verify that your working surfaces are clean and dry, as ink adhesion on glass and other non-porous materials decreases if they are wet or oily. Confirm that a 0.5mm line width matches the detail level your project requires. Ensure you can recap each marker promptly after use to prevent the tip from drying out. The 30-pack quantity suits high-volume environments such as schools or studios.

Sustained use behaviour

Ink flow remains steady during extended writing or drawing sessions without skipping or blobbing. Quick-dry formulation prevents smudging even when pages are handled immediately after marking. Fade-resistant pigment keeps lines bold on frequently touched items such as labels or outdoor signage. Regular recapping preserves tip performance across the full 30-unit supply.
