The Sakura solidified paint marker is a game-changer for industrial and scientific use. Based on my experience, it writes beautifully and easily on any surface, from metal to plastic. The pigmentation is incredibly vibrant and long-lasting, delivering an unmistakable mark that lasts. The low-temperature design ensures that it won't crack or degrade in extreme environments. The only downside is that it is hard to find in stores, but ordering it online makes it easy to get your hands on. This product is a fantastic addition to any adhesive and sealant toolkit.
