Imagine my excitement when I found the very same ZhuKe (bamboo shell) in Chinatown. All things in bamboo must be Puer. The Pinyin and Chinese characters are prominently displayed. However it is a famous herbal concoction for those with internal heat. It looks like shu but taste very different. I'd say each pod is about 30g. A package of 5 shells was only $3. I wished I could find puer packaged this way.
