Your highlighter's too broad for the fine notes you need, and your black pen doesn't give you that pop of colour for a coding system. The Artline Supreme Fineliner in lime green fixes that. A 0.4mm water-based ink tip draws a clean, precise line with zero bleed-through on standard paper. The glossy grip stays comfortable whether you're marking a single page or working through a full stack. It's one of 30 colours in the Supreme Fineline range, so your colour-coding system actually holds together. Want a thicker line? Grab the 0.6mm version of the same pen
