Adhesive-backed mailing seals are ideal for sealing folded flyers and brochures that do not need envelopes. 1" diameter seals dispense easily from a 3" core roll, fold conveniently for application, and facilitate easy opening of mailing without damage. Seals are designed for use with the Tatco Mailing Seal Dispenser (sold separately), which separates seals from backing for quick, easy use. Clear design allows the print underneath to remain visible so your entire message will be received.
