A Cha-koro is an incense burner made for room scenting by roasting tea leaves - especially Japanese green tea leaves - with a candle.
You can calm yourself with the scent of roasted green tea leaves. (It has an aromatherapy effect.)
The scent of green tea leaves roasted in a cha-koro eliminates odor in a room.
This cha-koro can also be an aroma oil burner.
Instruction: Put a spoonful of green tea leaves. Change tea leaves with new ones when they turn black.
Caution: Do not use a cancle with high amount of heat(high temperature). Use a candle which is the same type as the one used for aroma oil burners.
