The corporate client's seal that he had made earlier contained about 40 letters. Attempting 80 characters on a seal was stepping into unknown territory. "Carving out the letters is not the end of the story," Murao, 48, said. "A seal can only be called a seal when the characters are legible in its impression. We were concerned we may not be able to do that." However, the artisan spirit of the workers soon took over. "Although we were unsure if we could succeed, we decided to give it a shot," Murao said. "We also had the mettle as artisans who had made so many seals earlier."
