Chalky Crown Liquid Chalk Markers For Blackboards-Bold Color Dry Erase Marker Pens-Chalk Markers For Chalkboards Signs,Windows,Glass-6Mm Reversible Tip (8 Pack)-24 Chalkboard Labels Included

Despite being marketed to be used on blackboards, it does not wipe of clean. I even tried erasing with wet wipes but the mark remains. Disappointed in this - will buy real chalk instead.

These are not erasable though they are nice colors and easy to use. I used them on a nonporous chalkboard but it took real elbow grease to remove as much as possible-that some of the paint on the chalkboard came off-but still i can see remains of the ink.

These are great chalk pens and colours are vibrant. Easy to use and to wash off windows or mirrors leaving no residue, not sure of other surfaces though and did stain the white wood around the mirror I wrote on or should I say his elf wrote on lol should also not ive had them a year and haven't dried out or anything as of yet

Great value

Genial. Perfecto para uso infantil. No escurre, se limpia muy fácilmente. Si quieres decorar tu casa en Navidad con los niños, es súper divertido.
