Linkyo, Liquid Chalk Markers, these are amazing.  I love them.  Very easy to use, just push the tip, shake, push tip again and your ready to draw!  I cannot stop writing all over the windows and mirrors in my house, not even the fish tank was safe.  Very colorful colors.  They write very smoothly and evenly.  You will have just as much fun as I have.  Makes you feel like a kid again, but of course you can you these for more important things.   Thank you for allowing me to try your product  I recommend this product.  Disclosure: I received this product at a discount in exchange for my honest review.
