Good! I was looking for finer-tipped markers for my whiteboard calendar, and these fit the bill. They're not *super* fine, but they're easier to read when writing in smaller letters. There is a small amount of odor, but not enough to bother even my super-sensitive nose. The color is nicely saturated and dark. The click mechanism is very handy as well. I'd recommend these!
The Sanford Ink Company released its first wet erase marker for overhead projectors in 1965 with the product name Vis-à-Vis. Eleven years later, the company launched its first Expo-branded dry erase marker lines in black, red, blue and green colors with a chisel tip. Since then, Sanford has expanded the Expo brand to include fine point, ultra fine point, and bullet tip variations a well as new ink colors.
