Learn your States! What a great way to play and write on the walls. Use dry erase markers, permanent markers, crayons, chalk… even Sharpies and it will wipe right off with a clean cloth! Great for home, office or schools. No glue, thumbtacks, or Velcro needed, simply peel and stick to any flat surface. Incrediwalls has also been specifically manufactured to be removed and repositioned for up to 2 years (over and over again if you wish) without damaging your wall or leaving any sticky residue.
