These are in my opinion the most brilliant Polymer Acrylic paints on earth. I was a teacher in a University Art College for 25 years. An award winning painting I did 40 years ago was slightly damaged in a tropical storm, I needed to repair and repaint parts of the image. I needed the identical paint, as another acrylic paint used then to repair the work had faded over the years in the sub tropical light. But Chromacryl hadn't faded in 40 years! Mighty Ape stocked the original paints! I am now able to recreate the original colours and repair the damage knowing the new painting will not fade for 40 years or more.
