A 5 ml ink refill for the Tom's Studio Ori Refillable Highlighter, available in six fluorescent colors. The ink is formulated for strong color payoff and smooth flow through fiber-based tips, so highlights read clearly whether you're marking notes, planning spreads, or working through a dense page of text.

Compatibility varies by color. Green and Purple are dye-based and can also be used with the Tom's Studio Lumos in fiber and brush tips — but not with the Lumos fineliner or writing tips. Yellow, Blue, Pink, and Orange are pigment-based and are compatible with the Ori only; use in other Tom's Studio pens with reservoirs or fiber tips may cause clogging.
