#10 Security Envelopes for Business Mail

These white #10 envelopes are built for everyday business correspondence. A box contains 500 pieces, supplying offices that send invoices, statements or direct-mail pieces in volume. The gummed flap seals with moisture for a secure closure.

Blue Tint Holds Up Under Daily Use

The 24 lb. white wove stock resists tearing when folded and run through inserting equipment. Inside, a blue security tint blocks printed text from showing through even after repeated handling. The contemporary seam stays flat so envelopes feed cleanly in high-speed folders.

Address Window Saves Labelling Time

A 1-1/8" x 4-1/2" window sits 7/8" from the left edge and 1/2" from the bottom, displaying the recipient address without a separate label. Buyers who need a non-window envelope or a different paper weight will need another product.

Questions about this item

Does the 24 lb paper weight make the envelope stack heavy for all-day desk use?

At 24 lb stock the 500-count box stays light enough to keep on a shelf without strain.

What printer or inserter do I need to run these #10 window envelopes?

Any standard laser or inkjet printer that accepts #10 size feeds them through the manual or main tray.

Will the 1-1/8" x 4-1/2" window align with addresses printed on older letterhead templates?

The window sits 7/8" from the left and 1/2" from the bottom, matching the classic #10 layout used by most templates.
