Price is for one dragon ball.  Each ball is roughly 8g.
We managed to produce just under 3kg dried tea for our production.

Tongqinghe is located within the southernmost area of Yiwu's protected forest.  The natural wild forest has encouraged the 'gaogan' (tall trunk) tea trees to grow in this area and we have been producing tea from this region since it was discovered.  Due to low production in the region this, our production was considerably lower than in previous years, but this year's tea is particularly strong as a result.
 
When brewing these tightly compressed Dragon Balls, I recommend starting with a double rinse, 30 seconds each with at least a minute rest after each rinse.  This will help decompress and awaken the leaves and after that, you can steep as you normally would for standard gongfu brewing.
