Bung is the Thai name for a northern-style, bulbous vessel used to keep vegetable seeds. It is made from bamboo and coated with black lacquer, and has a square wooden base, and a round closure, so it can be sealed to prevent insects from infesting the content.

It is usually ornamentally painted, and has additional bamboo strips all around, that run vertically from the neck to the base. Since it originates from the North, it often has northern Thai script calligraphically painted on it, as is the case with this one.
