I had my own personalised Hangeul stamp made at Myung Sin Dang Art Shop at 18, Gwan Hun Dong Jong Ro Gu, Seoul.
Following a pingback from Jonathan Jamieson, I discovered a few blogs that cover these stamps much better than my effort here 😉 I also learned the stamps are called ‘dojang aka name chop‘ (도장).

The personalised hand stamp creates the red square which contains a transliteration of Doug Lawrence in Hangeul
Do you feel like royalty now?
Hi,
Where can I buy a Korean dojang?
Many thanks
