No, made in China.
Wisdom Arts seem to get an order approximately once a year.
2 or so years ago they commissioned 100 Shui Pin with the shop chop on instead of Gao Jian Jun's, when I arrived 18 months ago there were only 4 left of which I bought one (170 ml).
Last month when I arrived a new batch was in which had about 15 still unsold of 3 or 4 different shapes and sizes, there were only 4 small ones. 3 Days later 2 small ones had sold including a flattish shaped one that I had fancied buying for brewing Dan Cong. I immediately snapped up the remaining 2.
2 weeks later on my return from Langkawi and Penang a couple of the larger ones had sold, and another was in the process of being purchased.
Above shows the zhuni shi pao about to be sold ( I guess it is slightly over 200 ml) to the right a zisha shi pao that was an alternative prospect for the purchaser. The 2 Owners behind the table Ah Ming and May, a friend of may's at the end of the table who had popped in for tea and chat.
In the centre in white shirt a valued friend and customer, who had brought his friend in red shirt in to buy a yixing. Red shirt was nervous and excitable everyone else was calm.
Man in white had to leave, but as he got to the door a monsoon like rain started falling so he came back and helped steer his friend towards the zhuni.
Price of mine - well you know how to buy things in Malaysia I don't
the price tag was 450rm
Fortunately though I did not bargain in anyway whatsoever due to the shock of half the small ones having gone in 2 days
Ah Ming invoiced me for them at 300RM each because I am one of the 'in' friends
The girl at the front of the shop is the sales assistant who never gets involved in the back of shop tea parties but has to ply the front of the shop trade with passing tourists et al - she has her own little table for commercial TGY and Jasmine tea etc while at the back we are enjoying 30 year old sheng.
The owners however rarely get there when the shop opens, so if I arrive shortly after 10 in the morning the girl will take me to the back of the shop and start brewing some good stuff for me, I think she relishes these sort of opportunities.
