Although issued by Hongkong Post in 2023 under the umbrella of “Intangible Cultural Heritage” (seems quite tangible to us), these sets were not made available to the general public, at least not yet.  To get the set, customers needed to place a stamp order above a certain price for the upcoming Local Standing Order Service.   We did that and we got — one set.  Here it is.  Unused.  Grade: 1
