Business correspondence envelope

This #10 envelope measures 4.125 x 9.5 inches and uses 28-pound white sulphite paper with a vellum finish. The diagonal seam construction and remoistening seal suit everyday mailing tasks. A box contains 500 envelopes weighing 8.5 pounds total.

Capacity and headroom

The 500-count box supports high-volume office mailing without frequent reordering. Each envelope handles standard letter-size documents folded to fit the 4.125-inch width. Heavier multi-page inserts may exceed the 28-pound paper's tear resistance.

Postal standard limits

The #10 size meets standard business mail dimensions for automated processing equipment. The 92% brightness level ensures reliable barcode and address readability by sorting machines. No window design means addresses must be printed or written directly on the envelope face.

Questions about this item

Will #10 envelopes feed reliably through my older laser printer?

The 28 lb sulphite stock and diagonal seam are standard for #10 size, so most legacy laser and inkjet trays handle the 4.125 x 9.5 inch sheets without misfeeds.

How can I confirm the brightness matches the 92 % spec after opening the box?

Hold a sheet under daylight next to a known 92 % brightness reference; the white sulphite vellum finish should appear visually identical.

Does the box of 500 include any moisture-activated seal strips or must I buy them separately?

Each envelope already has a remoistening seal on the flap; no extra adhesive or sealing strips are required.
