The Founder General Choi required that everyone must know who is “in charge” in any class so he designed these badges and said that if you are recognised as an “Official ITF” instructor or authorised Assistant then you must wear a badge for everyone to see your formal identification — DETAILS – When buying you will get TWO of these (one for each shoulder) and we always recommend that you carefully pin each in the correct position then carefully stitch to secure your identity — AUTHENTIC – each badge is exactly as shown on page 745 of the Encyclopaedia (as shown) and they must be worn on each shoulder of your Dobok whenever you are teaching or assisting in any class — SIZE – these badges are all 9 x 9 cms.
