This was found in the warehouse of my family's liquor store. It was used to hold heavy items like 1.5L juice bottles for sale at the store. I believe it's built sturdy, but the strength has likely diminished due to age. There are bamboo splinters visible, as shown in image 4. I haven't cleaned it on purpose. Diameter of the opening is approximately 45cm, the base diameter is 25cm, and the height is 35cm.
