You need a marker that doesn't fight you. The POSCA Medium Brush Tip in Yellow gives you a semi-flexible nib that flows water-based pigment smoothly — fine 1mm lines for detail, up to 4mm for bold strokes. One tool. Layer, colour, detail. No drying out mid-sentence, no skipping on paper. It's the pen that makes 'I'll just add a bit of colour' actually happen
