Ticonderoga Vis-Aid Markers make overhead transparency presentations that grab your audience’s attention. A variety of bright, bold colors provide high visibility, while durable fine tips help ensure legibility. Low odor, water-based ink dries quickly for even, clear marks, then wipes easily from the transparency with a damp cloth. Vis-Aid Markers feature a patented thumb button cap for one hand cap release. They are AP certified non-toxic and conform to ASTM safety standards. More than a writing and art products company, Dixon Ticonderoga empowers people to take conscious and subliminal thoughts, facts, ideas and dreams, and preserve them using tools that are simply extensions of themselves.
