We bought these and I won't go back to the Walmart ones again. They were perfect, good security and not see through and the seal was super great. If you made a mistake sealing it, then you have to basically destroy it to open because you cannot open from the seam again. The best and great price for 500. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Envelopes *by R***Y on Reviewed in the United States on September 5, 2024* These #10 envelopes are perfectly designed with peel away sticky strips to seal them shut. The sides are opaque providing needed security. This is the third box I have purchased. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Great Value! *by J***. on Reviewed in the United States on April 21, 2021* I had not waste. All envelopes had great adhesion and were of sufficient quality for the job. Some reviews note adhesion issues - again, I had none and used all 500 of them on a mailing. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.th/products/87216420-valbox-500-count-10-security-self-seal-envelopes-windowless-design](https://www.desertcart.co.th/products/87216420-valbox-500-count-10-security-self-seal-envelopes-windowless-design) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-04-22*
