Crayola Take Note! 4 ct Chisel Tip Whiteboard Markers (Black,Blue,Red,Green)

I am a teacher and I have used every brand of whiteboard markers available and this brand is by far the most vibrant and long lasting brand of whiteboard markers I've used. The colors are vibrant and the amount of ink in the markers lasts a reasonably long amount of time, I purchased my last set of four a term and a half ago and I have just ran out of the ink. This will last me a good three months. Other markers barely last one month. Great value for price.
