The OEM Premier Envelope Moistener PRELM3 is designed for the efficient processing of envelopes and stamps. This all-purpose moistener easily moistens all sizes of envelopes in a single, mess-free pass. It features a separate area specifically made for applying moisture to stamps or fingers. The advanced cellulose wick pulls water from the bottom and remains moist for days, while the enclosed housing prevents splashing and protects the water supply from evaporation.
