Quality Park No. 9 Double Window Envelopes with Tamper-Evident Seal: Reveal-N-Seal tamper-evident closure

Shows tampering at a glance while protecting sensitive information.

Product Overview:

You still fold bills to fit envelopes and worry they arrived intact. Let me save you that nagging doubt and a few wasted calls. These No. 9 double window envelopes line up addresses so folding becomes predictable and fast. If you send invoices, statements or donor letters, this keeps the process tidy and reliable. They work for single-piece mailings and batches without extra prep or fiddly measuring. Made from twenty-four pound white wove paper with side seams, they feel substantial in hand. A reflex-blue security tint obscures contents, and a perforated self-seal clearly shows tampering. Picture a neat stack of sealed envelopes, the soft click of the seal, and fewer follow-ups.

Key Features:

• Reveal-N-Seal Tamper-Evident Seal: perforated self-seal shows attempted openings so you catch tampering before the contents leave.
• Double Window: top and bottom windows align with printed statements, saving folding time and reducing address errors.
• Security Tint: reflex-blue interior hides numbers even against bright light, protecting client data.
• Twenty-four Pound Paper: the heavier stock and side seams keep envelopes flat, reducing jams and giving a clean look.
• Moisture Resistant: coating resists damp edges during transit, so rainy pickups rarely ruin a batch.
