Ticonderoga® Vis-Aid® Markers make overhead transparency presentations grab your audience’s attention. Eight bright, bold colors – Black, Red, Blue, Green, Orange, Yellow, Purple and Brown – 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. The finish contains Microban® to inhibit the growth of odor and stain causing bacteria on the marker. AP certified non-toxic. Conforms to ASTM standards.
