I ran 5 through my laser printer and 2 came through successfully but severely warped on the plastic window. The third had the window completely melt and leave part of the plastic in the printer causing a jam. These cannot be used in a laser printer. **Q: Does the window has clear plastic cover?** A: Yes they do. I love these envelops for mass mailings. **Q: what is the size and location of the window from the left?** A: THE WINDOW IS 7/8" IN FROM THE EDGE OF THE ENVELOPE. THE WINDOW IS 1 1/4" IN HIGHT X 4 1/2 WIDE **Q: How far is the window from the left edge? How far from the bottom edge?** A: left edge 3/4 inch and bottom 1/2 inch ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Seal *by K***P on March 3, 2026* These were the envelopes I have searching for and Amazon had the best price. Even Walmart was overpriced. It didn’t take long to come. Quality was great. Thick but not too thick. Fits letters perfectly. Bought for payroll and they are so easy to use and do not peal up when sealed. Will buy again. ### ⭐⭐⭐⭐⭐ Great Value *by K***M on March 31, 2026* Great product and window is in the proper spot. ### ⭐⭐⭐⭐⭐ Best value envelopes for shipping small orders and invoices *by E***E on March 19, 2026* These are the best price per self sealing envelopes I could find for this size and quantity online or in person. I’ve purchased about 10 packs of 500 of these over time for my small business. They seal easily and securely without needing tape or moisture, which makes packing orders much faster. I also like that they are not see through in practice, even though they are labeled as security tinted. I use them specifically for shipping trading card game orders, and it helps add a bit of privacy so the contents are not obvious. I often ship smaller orders where tracking is not required, so keeping costs low while still using something clean and professional matters. These work well for that. The left window is also very convenient. I have to provide a printed invoices with customer addresses, and they line up perfectly in the window, which speeds up my packing process a lot. If you sell cards or other small items online, these are a solid budget-friendly option that makes order fulfillment quicker and more efficient. Pros: Best price per envelope I could find for bulk quantity Self sealing works well and saves time Not see through in real use, good for privacy Window aligns well with printed invoices Speeds up packing process for small orders Cons: None so far ## Frequently Bought Together - Amazon Basics #10 Security-Tinted Self-Seal Business Envelopes with Left Window, Peel & Seal Closure - 500-Pack, White - Amazon Basics #10 Security-Tinted Self-Seal Business Letter Envelopes, Peel & Seal Closure - 500-Pack, White - Amazon Basics Multipurpose Copy Printer Paper, 8.5" x 11", 20 lb, 8 Reams, 4000 Sheets, 92 Bright, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/45325878-10-security-tinted-self-seal-business-envelopes-with-left-window](https://www.desertcart.co.uk/products/45325878-10-security-tinted-self-seal-business-envelopes-with-left-window) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-01*
