The pressing of teas was considered an art form that dates back to the Song Dynasty 960-1279 BC. Tea creations were never meant to be permanent, instead serving to represent the impermanence of life, love and happiness here on Earth. The cup of tea produced from these hearts is dark, with deep notes of wine and subtle earth, full body and medium long finish. Best enjoyed in the company of someone special! 1 tea heart = 1 cup of tea A combination of fibers of soya silk (a bi-product of tofu production), bamboo, silk, recycled aluminum can fibers, and recycled polyester fibers have been used in the construction of this unique card.
