Mr. Pen Black Fineliner Pens 4 Pack 0.5mm Blue

Four-pack fine-point pens

This set contains four black fineliner pens with a 0.5 mm tip that produces consistent, fine lines. The oil-based ink dries quickly and is formulated for transparent sticky notes. It is not recommended for thin Bible pages because bleed-through can occur. The pack suits students, office workers and hobbyists who need reliable everyday writing tools.

Permanent oil-based ink limits

The ink is permanent once dry, so mistakes cannot be erased or washed away. It performs well on standard paper and transparent sticky notes but may feather on very thin or coated surfaces. Users should test on a sample sheet before committing to final artwork or archival documents. The fine tip does not lay down broad strokes, limiting its use for large-area colouring.

Transparent barrel and fine tip

Each pen has a clear barrel that lets you see the remaining ink level at a glance. The 0.5 mm needle point holds its shape during extended writing sessions and resists splaying under normal pressure. Caps snap on securely to prevent the ink from drying out between uses. The lightweight design reduces hand fatigue during long note-taking or drawing sessions.
