This lot is wrapped in yellow paper and crafted from fifth-grade tea leaves that have undergone wet piling fermentation. The processed leaves are then compressed into a brick using red tea powder. The 73 brick is recognized as a precursor of ripe tea and holds the distinction of being one of the oldest and rarest versions available in the market.
