Its dense pigmentation adheres perfectly to mirrors, windows, and dark panels, without releasing the characteristic dust of traditional chalk. The deep blue color conveys a professional and elegant image, making it ideal for highlighting announcements in the office, personalizing shop windows, creating offer boards in restaurants, and carrying out artistic works.
