Expo's chisel tips lay down bold, visible lines that remain legible across conference rooms and classrooms. These markers handle everything from quick notes to detailed diagrams, with consistent ink flow that won't fade mid-presentation or skip during extended writing sessions. The low-odor formulation matters during long meetings or all-day teaching sessions, you get vivid color without the harsh chemical smell that standard markers produce.

Chisel tips offer versatility: use the broad edge for filling large areas and headlines, rotate to the narrow edge for detailed writing. Ink erases cleanly from whiteboards and glass without ghosting or requiring aggressive scrubbing. AP-certified nontoxic ink meets safety standards for classroom use.

Four-color sets provide essential working colors for most applications. Eight-color sets add yellow, orange, purple, and brown for color-coding systems, visual hierarchy, or more expressive diagramming. Markers work on any non-porous surface, whiteboards, glass panels, laminated charts. Whether you're mapping project workflows, teaching mathematics, or facilitating design reviews, these markers deliver the reliability that keeps presentations moving forward.
