This box of 12 markers are by no means cheap ($20.95 Amazon price at the time of this review), but quality dry erase markers - frankly - rarely are (so expect to pay at least $1.50 per marker).
But if you are willing to pay the price these are really good markers. First, the "ink indicator" is invaluable. Granted, it's not a "make or break" feature unless you're in the middle of an important presentation and your marker runs dries (I bet many of you reading this has had this happen at least once).
Second, the ink is quite good. The color (green) is sharp and "deep" enough to be seen clearly from a distance. And it wipes off easily.
Third, the odor. There is no odor. Yes, there is a slight marker smell, but not the overpowering odor we've come to expect with dry erase markers.
Nice. Not cheap, but you'll get excellent results. 4 stars.
Expo Dry Erase Marker with Ink Indicator features a clear barrel with built-in Ink Indicator that makes it easy to see the amount of ink left at all times. Now you can always be prepared to effectively communicate your message. Available in chisel tip for broad, medium or fine lines.
