Blue Bottle Coffee's limited-edition green cup quality control fails: Controversy over hand-glazing and differences in cup-bottom markings in China spark heated discussion

Blue Bottle Coffee recently launched a 2023 holiday limited-edition pine green mug in Japan, which quickly became a hit in collector circles thanks to its high aesthetic appeal. After the China region officially announced its release on November 5, the mini-program sold out instantly, with many enthusiasts going so far as to use international proxy shopping services or visit physical stores just to get one.
