Bright ideas deserve bright ink. These Highlighter Inks are designed to work seamlessly with the Ori Refillable Highlighter, delivering bold, high-impact colour with the flexibility of a refillable system. Vivid, punchy and made to be used generously, they bring instant clarity to notes, plans, sketches and creative thinking. Available in six fluoro shades, each ink is formulated for strong colour payoff and smooth flow through fibre-based tips. Whether topping up an Ori or experimenting with colour in calligraphy or dip work, these inks are made to stand out on the page. The highlighter inks divide into two categories: Green and Purple are dye-based, while Yellow, Blue, Pink and Orange contain pigments for vivid colour. Pigment-based inks are generally not compatible with other Tom's Studio pens and may cause reservoirs or tips to clog—with the exception of calligraphy and dip pens. Green and Purple highlighter ink can be used with the Lumos in fibre or brush tips, but are not suitable for the Lumos fineliner or writing tips.
