Cassia bark comes to the factory in its raw form. Upon drying, they curl inwards from the outer edge into round sticks. Usually it is single curled because of its thickness. Thin bark can curl from both edges making it double curled sticks. The length of the sticks may be up to 1 meter and the thickness of bark is between 1-4mm. Our cassia is sorted manually in different grades depending on its thickness, colour and quality.
