#9 (3-7/8″ x 8-7/8″) – Double Window Envelope (Flip-N-Seal)

#9 Double Window Envelope with Flip-N-Seal Closure

This #9 envelope (SKU ENV-3FNS) is 3-7/8″ x 8-7/8″ with two windows positioned for standard laser check layouts, so the payee address and account information line up without hand-addressing. An interior security tint covers the contents so figures don’t show through blank areas of the paper.

The closure is Flip-n-Seal: the envelope ships open with a long flap opening, and the flap flips over and seals without moistening or a separate adhesive strip. Confirm the window measurements against your check layout or software output before ordering, since placement varies by program.
