Regular price $509.71

This is our most popular double window envelope - ideal for checks. It is a hybrid size called a# 9 1/2 which is the width of a #10, but the height of a #9 envelope. The greater width is designed for trouble free inserting while the lesser height reduces wiggle room and therefore, reduces show through of confidential information on checks.
