It's good tea, has good taste and qi, and should age nicely.

I'm very happy to have found such a good tea at such a friendly price and one that serious drinkers such as Teaism thought enough of to buy. I've joined the masterclass

One more thing--Khun Zhang's price of 2,300 baht is the price everyone agreed to sell it at, but I know of at least one Malaysian vendor who charges more than that. Khun Zhang ships worldwide and the USD is at a six-year high against the baht. Carpe diem
