Quality Park No. 10 Window Security Tinted Envelopes with a Self-Seal Closure: secure, self-sealing envelopes for standard business mail

Redi-Strip closure seals without moisture and keeps your mail looking professional.

Product Overview:

You want mail that looks tidy and stays private. These No. 10 single-window envelopes use a Redi-Strip self-seal so you don't need to lick anything, and the security tint hides contents when held to light. They're made from 24 pound bright-white wove stock, so printed addresses show crisp and legible through the standard window. If you send bills, statements or invoices, you'll notice fewer misreads and less fuss at the mailbox - picture envelopes arriving neat, sealed, and ready to file.

Key Features:

• Redi-Strip self-seal: Peel and press the strip for a secure, no-moisture closure that saves time and keeps envelopes shelf-stable.
• Single window: The standard window aligns with printed addresses so you skip handwriting and speed up mail runs.
• Security tint: The interior pattern conceals information when held to light, protecting account numbers and private details.
• 24 lb bright-white stock: Heavier wove paper gives a clean, professional look and resists creases during handling.
• 500 per box: A full-box supply cuts reordering frequency so your mail prep stays uninterrupted.
