You have a choice of 24 illustrations (17 characters) for the "Detective Conan Hanko Collection". The 17 characters include Edogawa Conan, Kudou Shinichi, Haibara Ai, Kaitou Kid, Akai Shuuichi, and Amuro Tooru.
There are 3 fonts you can choose from, including an orthodox font, which matches the fascinating characters, and a cute font.
Not only can you make it with your sir name or first name but you could also make the seal with old-style letters, pen names, handle names, and even messages like "OK", "見ました" (confirmed), "ありがとう" (thank you). (The letters allowed are 3 for Kanji, 5 for Hiragana/Katakana, and 6 for the alphabet. You can also use the names of the characters just like in the image.)
You can choose from the wood type or the black buffalo-horn type, which can be registered at most of the banks throughout the country, or the SLAT-G type, which you can use for receiving deliveries, as a signature for memos, for putting your name on your belongings, or just using it as a stamp for your children's parent-teacher notebook. The wood type and the black buffalo horn type comes with a special case of which design you can choose from the 17 characters.
