My 2nd time purchasing these, but this time in black because they were on sale for a reasonable price and had prime shipping, I was disappointed the blue ones were not; didn't make sense. Thickness is pretty good, they're not see through so couldn't see what you're shipping. Adhesive seal is good, but I always go back and tape over seal for extra caution.

These are lightweight and thin but seem strong and durable. (Not nearly as thin as some others I have used). They are true to size and fit great for my needs. The self-adhesive closure is easy to use and effective. They are very flexible and easy to fold to fit in your mailbox or tape them up shorter if you need a smaller bag. Great value for the set and a great product. ## Frequently Bought Together - UCGOU Poly Mailers 14.5x19 Inch White 100 Pack Large Shipping Bags #7 Strong Thick Mailing Envelopes Self Sealing Adhesive Waterproof and Tear Proof Boutique Packaging Postal for Clothing - UCGOU Poly Mailers 19x24 Inch White 100 Pack Extra Large Shipping Bags Strong Thick Mailing Envelopes Self Seal Adhesive Waterproof and Tear Proof Boutique Postal for Clothing Quilt and More - UCGOU Poly Mailers 10x13 Inch White 200 Pack Shipping Bags #4 Strong Mailing Envelopes Boutique Packaging Postal Self Seal Adhesive Waterproof and Tear Proof Small Business for Clothes Books --- ## 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.kg/products/329218061-ucgou-14-5x19-white-poly-mailers-100-pcs](https://www.desertcart.kg/products/329218061-ucgou-14-5x19-white-poly-mailers-100-pcs) --- *Product available on Desertcart Kyrgyzstan* *Store origin: KG* *Last updated: 2026-04-23*
