WESTERN STATES 6.5" x 6.5" 28# White Square Envelope Box of 500

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.
