This cup is part of the Shan Collection Series, the stamp is at the bottom. This Series is a special collection from Shan Kiln Ruyao Studio. Both the body and glaze use special formulas which make the material very difficult to fire properly. As a result the scrap rate during firing is quite high and there is a very limited quantity - no more than 100 in a year, which is around 25 each season - in the market. Because of the limited availability we do accept a limited number pre-orders for this series.
There is an authenticating sticker on each product in this series to guarantee it is an authentic Shanming Series piece. Each piece will have an Anti-Forgery sticker on the surface. To guarantee it is an authentic piece, scrape off the cover of the sticker to reveal the security code and check its validity on the China Commodity information conformation Center website http://www.china12-315.net/
All pieces are delivered in a gift box and include the collector's certificate with Mr. Lee's signature.
