Seals

There are three types of seals:

Nintei-hin (認定品) – “Approved item” may be used for all competitions and level tests.  Goes through very rigorous testing including but not limited to size, paint durability, quality, etc.  (Common usage “Nintei seal”)

Suishō-hin (推奨品) – “Recommended item” color generally matches the Nintei seal of a given manufacturer example: Gentosha = red; Yamagata Koubou = yellow; Goes through the same rigorous testing as the Nintei seal kendama; may be used for testing up through Jun-shodan.  (Common usage “Suishō seal”)

Tokubetsu Suishō-hin (特別推奨品) – “Special Recommended item” colors and designs vary, may be used for testing up through Jun-shodan.  Does not go through the same rigorous testing as the Nintei seal kendama; generally given for works of art, very high priced kendama, or those of exclusive/limited release.  Has the seal but is not often something that is used/played.  For the Nintei/Suishō different colors usually mean different manufacturers but that is not always with the Tokubetsu Suishō style of seal.  Another example of this

seal is the 40th Anniversary seal released in 2015. (Common usage “Tokubetsu Suishō seal”)
