Review on Liquid Chalkboard Window Chalk Markers 12-Pack - Erasable & 🎨 Vibrant Colors - Safe & Washable Pens for Kids & Adults by Nicole Mcleod

I have never left anything other than 5 star reviews on Revain purchases but these pens have been useless! I bought these to write on my daughter's car windows for Seniors Day. I washed and dried the windows thoroughly the day before, primed the handles the day before AND the morning of Seniors Day. They hardly wrote on the windows. They were SMALL, TOO SMALL for car windows. I used both ends of the lace to see if it made a difference. It's not like this. Several pens ran out of ink before they could write even a small word on the window. It all looked awful because we were trying to make the letters stand out with tiny markers. There was no "post-processing". It was REALLY hard to get the ink out unless you put pressure on the tip (like a primer) which would cause the ink to bleed all over. It was just a disaster. If you need chalk pens to be reliable or useful, don't buy them.
