Quality Park® #9 Double Window Envelopes display both sender and receiver addresses for mailing statements and invoices. These security envelopes have a reflex blue pattern that protects sensitive client information because it obscures the details of the contents, even when held up to light. These 24 lb white wove envelopes have side seams for a clean, professional look. Each business envelope is 3-7/8 inches x 8-7/8 inches with a moisture seal commercial flap. The top window measures 1-3/16 x 3-1/2 in, positioned 3/8 in from the left and 2 in from the bottom; bottom window measures 1 x 4 in and is 3/8 in from the left and 1/2 in from the bottom. Stock up on boxes of 500, so you don't run out!
