Double Window Redi-Seal Security-Tinted Envelope, #9, Commercial Flap, Redi-Seal Adhesive Closure, 3.88 x 8.88, White, 500/BX

• Double window envelopes display sender and receiver addresses for invoices and billing statements.
• The uniquely designed Redi-Seal® self sealing closure requires no moisture; envelopes have double flaps that press together for an instant seal.
• Protect sensitive client information with a reflex blue pattern that obscures the details of the contents, even when envelopes are held up to light.
