#9 Double Window Laser Check Envelope – Self Seal – 3-7/8″ x 8-7/8″

#9 Double Window Envelope with a Self-Seal Closure

This #9 double window envelope (SKU ENV-4SS) measures 3-7/8″ x 8-7/8″ and is built for mailing laser checks whose payee address and return information already appear on the check itself. Both windows are sized and positioned to standard laser check layouts, so the envelope goes straight from printer to mailbox without hand-addressing. The envelope is white with an interior blue or black security tint, so account numbers and dollar amounts on the check inside stay covered.

Closure is a self-adhesive latex (Pres-Stik-style) strip: fold the flap down and press to seal, with no moistening step. Before ordering in bulk, compare the window measurements below against your check layout — window placement varies between software vendors, and a mismatch means the address prints in the wrong spot.
