POSCA Medium Brush Tip Marker – Blue | 1–4mm Water-Based Pigment

You want blue that isn't just a thin pen line or a flat wash. This POSCA medium brush tip in blue flexes from 1 mm precision strokes to 4 mm confident fills. The semi-flexible nib lets you tighten up for small text or open out for a bold border without putting the pen down. Water-based pigment flows even, layers over itself, and keeps your blue looking like blue – not a muddy grey after the second pass
