FAQs:

  • What is a windowless plain envelope? A windowless plain envelope is a standard envelope without a transparent window. It provides a blank surface for addressing and sealing, suitable for mailing documents, letters or other flat items securely without revealing their contents through a window opening.
  • What envelope sizes fit through a letterbox? Standard envelope sizes that fit through letterboxes in Ireland typically include DL (110mm × 220mm) and C5 (162mm × 229mm). These sizes are commonly used for posting letters, invoices and documents and are designed to fit easily through standard letterbox slots.
  • How do you use self-sealed envelopes? To use self-sealed envelopes, simply insert your documents, letters or items into the envelope. Peel off the protective strip covering the adhesive on the flap, then press the flap firmly against the envelope to seal it securely without needing additional moisture or glue.
