LC Long Cam Coffee Filter Size: The outer diameter of the part that holds the coffee beans is approximately 60mm. The thin paper outer box is slightly crushed, and although unused, the top lid is not in perfect condition, so the price has been reduced. There are no issues with brewing coffee, so please feel free to use it for everyday use. If you purchase the other item I have listed as well, I will upgrade the shipping method to Yu-Packet Plus!
