#10 Large Window Envelope with Black Tint All Purpose Window – ENV-10LW3133WS

#10 Large Window Envelope for Statements and Invoices

This #10 envelope (SKU ENV-10LW3133WS) uses one large all-purpose window instead of a custom-cut window, which makes it a practical stock choice for mailing statements and invoices without ordering a special printing run. It measures 4-1/8″ x 9-1/2″ and is made from SFI-certified white Western Sulphite paper with a black Wesco security tint on the inside, so printed account details stay hidden outside the window opening.

Construction uses two side seams under, and the flap closes with a traditional moisture (gum) seal — moisten and press to seal. Because the window is large and centrally placed, it works with a range of statement and invoice layouts rather than one specific software program.
