Authentication stamps for martial arts certificates

Martial Arts Dojo Certificate Stamp

Good Characters fashions its stamps after the authentic stamps of China, Korea, and Japan. The Dojo stamp is inspired by the Great Seals—the national seals—of the Republic of China and the Republic of Korea, which have thick borders.

Martial Arts Master Stamp

Nine-Character Stamp™ only at Good Characters: Nine is a mystical number in China. It symbolizes eternity. It’s said that a dragon has nine sons. There are nine types of dragons. The Forbidden City, the imperial palace of the Ming and Qing dynasties in Beijing, is said to have 9,999 rooms (although the actual number depends on how one defines a room). Thus, a nine-character stamp is one of our most popular. No matter how long or short your name is, our Chinese naming experts can create a nine-character representation of your name (and title, if you wish) and rank and style for your master signature seal.
