Abstract
A housing confines therewithin a saturated sponge, the same disposed for moistening the flap of an envelope. Too, the housing has a entry slot for an envelope, and a switch, with an operating sensor or limb which detects the entry of an envelope into the housing, for the purpose of rotating rollers which (a) move the envelope from the entry slot to an exit, and (b) cause the flap to wipe across the sponge and seal against the body of the envelope.
