The royal staff or Than Phra Kon (Thai: ธารพระกร) is one of the five royal regalia[1] of the King of Thailand.
The staff is made of cassia wood and enclosed at both ends in gold.
It has a length of 118 cm (46 in).
One end has a knob and there are three tines at the foot.
The royal staff is used as a symbol of regal authority as in other cultures around the world, and is associated in Thailand with the guiding of the king's footsteps down the path of justice and equity.
