About this product
Prepare invoices, payments and other mailings with these Quality Park Redi-Seal self-sealing #10 single-window security envelopes.
Protect sensitive documents with these security envelopes. The blue-tint interiors shield items from view, while the clear windows let you address letters without the need for labels. The convenient peel-and-seal adhesive closures keep paperwork securely tucked inside. With a woven white design, these Quality Park Redi-Seal envelopes provide a neutral background for address labels, postage and custom stamps.
- Envelopes are great for mailing letters and documents
- Made from 24 lbs. white paper for durability
- These envelopes measure 4 1/8" x 9 1/2" in size, providing enough space for your mail
- Redi-Seal closure with commercial flap seals securely without moistening
- Security tinted pattern helps to discourage reading sensitive information through the outside of the envelope
- Convenient box of 500 envelopes ensures ample supply
- Simply position the address to show through the single-left window
- Double-flap design keeps gum from sticking before use.
- Made in the USA
