Quality Park No. 9 Double Window Envelopes - Security Tint - 500/Box

No. 9 Double Window Envelopes are designed to efficiently display both sender and receiver addresses for mailing statements and invoices. These envelopes feature a reflex blue pattern that safeguards sensitive client information by concealing the contents from view, even when held up to light. Crafted from 24 lb. white wove paper, these envelopes boast side seams that contribute to a polished and professional appearance. The gummed flap closure ensures secure sealing upon moistening. Measuring 3-7/8" x 8-7/8", these envelopes are equipped with a top window (1-3/16" x 3-1/2") positioned 3/8" from the left and 2" from the bottom, along with a bottom window (1" x 4") located 3/8" from the left and 1/2" from the bottom.
