I’ve used these for about a year and had no issues. Hope that helps. **Q: Will shipping labels stick to these?** A: Absolutely! I only use adhesive postal labels. Have never had a problem. Be careful placing it straight or without wrinkles, you won't get it off! **Q: Can a mens hoodie fit into these?** A: A men's hoodie depending on the size will be too big to fit in this polybag. A medium men's hoodie may fit but anything larger will be too much fabric. I use these bags for shirts (dress shirts, t-shirts) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good quality mailers. *by M***K on August 8, 2026* These are very strong poly mailers.

Dark color, you can’t see in the packages. Quality is good, seems study enough. The self sealing glue is great, I had to open a package after sealing and it was super hard to rip into. ## Frequently Bought Together - KKBESTPACK 100 Large Poly Mailers 10x13 Shipping Bags for Small Business – Self Sealing Package Envelopes (10 x 13 Pack of 100, Black) - 9527 Product Fanfold 4 x 6 Direct Thermal Labels White Perforated Shipping Label, 500 Labels per Stack,1 Stack - KKBESTPACK Poly Mailers Shipping Envelope Self Sealing Bags (12x15.5 100pc) (PM100), 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.jp/products/169865251-kkbestpack-black-poly-mailers-10x13-in-shipping-bags-100-pcs](https://www.desertcart.jp/products/169865251-kkbestpack-black-poly-mailers-10x13-in-shipping-bags-100-pcs) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-18*
