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.
