Durable copper construction: The character grains are made of strength copper, keeping a stable shape during use. That durability helps maintain consistent impressions and preserves the appearance of the characters over time, reducing signs of wear from handling and external exposure. Fully interchangeable characters: Choose different numbers and letters to create any meaningful combination you need. The grains are easy to swap on the printing wheel, so you can change codes, dates, or serials quickly without special tools. Spacesaving, organized storage: All character grains and the printing wheel store neatly inside a compact carrying case. The organized layout protects pieces when not in use and minimizes the space needed on your bench or in a toolbox. Portable and ready to use: The complete set — character grains plus printing wheel — fits in one lightweight case, making it convenient to take to job sites or move between workstations. Set up and changeover are fast, so you spend less time preparing and more time working. Key attributes Material: strength copper character grains for stability and lasting appearance.
