  • Convenient and Professional
Size: 500 Count
I recently purchased the #10 Envelopes Letter Size Self Seal, Business White Security Tinted Peel, and Seal, and I couldn't be more pleased with the quality and convenience they offer. The self-seal feature is a game-changer. No more dealing with messy adhesives or licking envelopes—peel off the protective strip and press to seal. It saves time and ensures a secure closure every time. The robust peel-and-seal mechanism provides confidence that your documents will be safely enclosed. The business white color gives these envelopes a professional and polished look, suitable for various purposes. Whether you're sending out invoices, business correspondence, or personal letters, these envelopes convey a sense of professionalism that will leave a positive impression. The security tint adds an extra layer of confidentiality to your mail. It prevents prying eyes from seeing sensitive information inside, giving you peace of mind when sending confidential documents. This feature is essential for business use, where privacy and security are paramount. The letter size is perfect for standard documents, and the envelopes are well-constructed with a sturdy feel. The paper quality is excellent, balancing durability and a clean, professional appearance. They are also compatible with most printers, making it easy to customize and print addresses directly onto the envelopes. The #10 Envelopes Letter Size Self Seal, Business White Security Tinted Peel, and Seal are a fantastic investment for anyone looking for reliable, convenient, and professional envelopes. The self-seal feature, security tint, and high-quality construction make these envelopes stand out. I highly recommend them for both personal and business use. ... show more

  • Perfect envelopes
Size: 500 Count
I do a lot of mailings for our Property Owners Association and needed a supply of envelopes quickly. These envelopes are heavy material and secure. The seal peels off easily. The big plus was that I received them the same day! Great product.

  • Have tape on hand
Size: 500 Count
These are decent envelopes for the money. I will say that the adhesive does NOT go end to end so you may want to add a little piece of tape. Sometimes the sorting machine at the post office will snag on an end piece not fully sealed. They aren't sheer at all, so no worries about your privacy being invaded. I was told after reviewing five orders I'd be told a joke. This is my five. Better be a decent joke... ... show more
