Square glass travelling inkwell with heavy brass top. The uniqueness of this inkwell is in the way the top closes so that the ink will not leak. On the top is a small button. In the lid is a crevice all around that traps the small button. In order to open the lid, one needs to turn the top until a small opening is aligned with the button. The glass well is in very good condition with no chips or nicks. The lid is missing the inner plug. Overall height is 4 cm (1.5 inches)
