Liquid Chalkers are a very bold, white liquid chalk that comes in a pen, there are 4 pens in a package. With the pen you are able to get a thinner, sharper line if you are writing or drawing. If you prefer a thicker line just lay the pen a little on its side as you write. I received these Liquid Chalkers for review from Paper & Twine and they are excellent for writing on a dry erase board, car windows, chalk boards and mirrors.
