Since pencil coating chemicals are generally acidic solutions, the parts that transmit the current are made of platinum. In each item, 1 to 2 grams of platinum is used. The platinum surrounding the plastic material is deformed over time due to chemical corrosion and high corrections. Our platinum-plated titanium pens are plated by a professional titanium anode manufacturer. The sockets of our products are produced using quality parts of the German company Hirschmann to provide our customers with an exceptional purchasing experience.
