20 Pyramid sachets in a tin. Pyramid sachets offer the quality and flavor of loose leaf tea with the convenience of a tea bag. Our pyramid sachets are made of cornstarch material and are biodegradable. The tag and string are attached to the pyramid sachet by an ultrasonic sealing process. So is the sealing of the bag itself. There is no glue or staples like a conventional tea bag. Unlike conventional tea bags, pyramid sachets have more room for the tea leaves to unfurl and expand and yet have sufficient space for water to penetrate and infuse the leaves, thereby releasing the flavors in a very efficient manner. Therefore tea leaves of larger size can be conveniently used unlike the small Fannings type leaves in conventional tea bags. Because of the transparent nature of the material, loose tea packed in pyramid sachets are visible and therefore only high-quality tea leaves are used. Dust and other extraneous particles are not found.
