Abstract
A moistener for applying liquid to an envelope, for use in sealing the latter, comprises a liquid storage tank (70a, 70b) and means, such as wicks (71) for transporting the liquid to the envelope (not shown). The level of liquid in the tank is visible to a user through a window (73). In use of the moistener it is fully inserted into a housing (not shown) but with the window visible to the user. Partial removal of the moistener from the housing permits the tank to be filled with liquid via an opening (76).
