This lot is part of the rare early Blue Mark collection which has been stored in optimal conditions. Originally, the packaging was labeled with "Grade A" or "Grade B" for grading purposes, but they were ultimately covered with blue ink because all the tea cakes were of exceptional quality. This gave rise to the name "Blue Mark," alongside the esteemed Red Mark teas. The tea cakes showcase shiny, thick tea leaves with clear buds and a deeply embedded inner ticket. Due to limited market supply, their value has steadily increased over time.
