Thank you for looking. This is the "Inktense 72-color set" from the high-end art supply brand DERWENT in the UK. ■ Features It is characterized by its vivid colors, and when dissolved in water, it becomes transparent like ink. Once dry, it becomes water-resistant, making it easy to layer colors and a colored pencil that can be used on fabric and other materials. Since these are good art supplies, I would be happy if they could be passed on to someone who can utilize them! Thank you.
