Review on 6Mm Reversible Tip Neon Chalk Markers, 12 Assorted Colors Wet Erasable For Black Board Signs, Car Window Mirror Glass Non-Porous Surface - Liquid Chalkboard Marker Pens by John Patel

In the photo, you can see where I drew some shapes on top using regular colored chalk. It looks fine, but tends to be smeary and less sharp.In the bottom part of the photo, I drew similar shapes using some of these markers (didn't use all the colors, though! This also has more colors than a regular box of colored chalk). You can see how the lines are even, bright, and sharp. This is good for drawing, but it also makes any writing you do on the chalkboard more legible.They were as easy to remove as the regular sticks of chalk, with a chalkboard eraser, or for a more complete cleaning, a wet rag.
