Kotodo Takahashi Works was established in 1910 and has been specializing in the production of airtight iron cans.
After more than a hundred years of history and countless users, The iron cans of Jiangdongtang seem simple, but they contain many details.
Inside the airtight tank, there is also a golden airtight cover to further block the entry of moisture from the outside. The cover is made of higher-standard metal to prevent its expansion and contraction from temperature and humidity and affect the airtight function. In order to perfectly demonstrate its airtight function, and to be able to open and close smoothly, each lid will be adjusted and polished by the craftsman according to the slight difference of the can.
In order to prevent users from hurting their hands, the staff of the factory gently rolls each side of the tank inwards to make each side smooth.
