Painting and coloring are always best choices for family time and kids’ early education with our reusable giant coloring poster. We use a material which is water proof and can repeatedly be colored. We print the illustration on this material and use zero dust chalks and liquid chalks to color. It’s okay if the children’s coloring is wrong or mistakes are made; You can easily wipe off the traces thoroughly with a damp cloth. And the poster could be colored over and over again! It is very environmentally friendly. The dust-free chalk collocated in use is a patented product which is food safe, suitable for little kids for coloring and painting. You do not have to worry if kids bite or eat it accidentally, so mom and dad can be more assured for children to use.
