Square 6.5" envelopes for mailing and invitations

These white sulphite envelopes measure 6.5 inches square and come in a box of 500. The 28 lb stock with vellum finish suits everyday correspondence, greeting cards and small flat items. SFI certification confirms responsible fibre sourcing for buyers who track supply-chain standards.

Side-seam construction and remoistening seal

Two side seams under the body keep the square shape flat in postal equipment. The 1.875 inch square flaps use a traditional remoistening adhesive rather than peel-and-stick, so sealing requires moisture each time. No window means the full face is available for handwritten or printed addresses.

92% brightness on 28 lb sulphite stock

The bright white surface handles laser and inkjet printing cleanly for typical office volumes. Heavy card inserts or multi-page bundles may exceed the single-sheet weight the 28 lb paper is designed to carry. Bulk mailers needing larger quantities will need multiple boxes.

Questions about this item

Which box quantity should I choose for regular office mailing?

The box contains 500 envelopes, a practical count for ongoing correspondence without frequent reordering.

What does the 28# paper weight mean when the envelope is in use?

At 28# the sheet feels substantial, resists curling in laser printers and protects contents without adding bulk to postage.

How does the remoistening seal work with the 1.875" square flap?

The gummed flap activates with moisture, creating a secure closure across the full 1.875" width for reliable sealing.
