Quality Park Reveal-N-Seal #10 Security Tinted Business Envelopes in white wove, 500 per box. These standard #10 envelopes measure 4 1/8" x 9 1/2" and are made from durable 24 lb. white wove paper.

The patented Reveal-N-Seal closure design features a unique flap that folds up and into place for a firm, reliable seal without premature sticking or peel-strip waste. The blue-tinted interior security pattern helps discourage reading of sensitive information through the envelope, making them suitable for mailing personal and confidential business documents.
