Open End Catalog Envelope 4 x 6.375

These white kraft envelopes measure 4 by 6.375 inches and feature an open-end design with a center seam. The 24# paper stock provides reliable durability for everyday mailing tasks. They are SFI certified with 84% brightness and a vellum finish. Each box contains 500 envelopes suited for catalogs, booklets, or documents.

Easy remoistening seal application

The flap-down closure uses a traditional remoistening seal that activates with moisture. No special tools or equipment are needed to secure the contents. Ensure the flap is pressed firmly after moistening to prevent the seal from lifting during transit. Humid storage conditions may cause premature sealing of unused envelopes.

Verify document dimensions before ordering

Confirm that your inserts fit within the 4 by 6.375 inch envelope size to avoid folding or creasing. The open-end style works best for materials inserted from the short side. Check that the center seam construction meets any specific mailing regulations you must follow. These envelopes have no window for address visibility.

Questions about this item

How can I confirm the envelopes seal properly after moistening the flap?

Press the moistened flap firmly along the center seam and hold for a few seconds; the remoistening adhesive bonds on contact, creating a secure closure without tape.

What comes in the box and is anything else needed to mail them?

The box contains 500 open-end catalog envelopes measuring 4 x 6.375 inches; you only need to add postage and any address labels or ink for writing.

Which version should I choose if I want the standard white kraft with vellum finish?

The listed item is the single specification — 24 lb white kraft, SFI certified, 84 brightness, vellum finish, center seam — so there are no alternate versions to select.
