What about if I used one to wrap the book and then another to put it in, then ship? Thx** A: As an online seller, I do ship heavy items in these bags, but I double and sometimes triple the bags to ensure they don’t break. Now, I’ve never shipped heavy books, but I’ve slid heavy boxed items in these bags, as I buy various sizes of them, and I’ve shipped heavy bags of clothing weighing almost 20lbs. These bags are pretty sturdy. I think you’d be alright double bagging a heavy book in these. Plus, they look nice. **Q: The price is very attractive, is it easy to tear?** A: I have shipped clothing items and had no complaints about the packaging **Q: Is the a suffocation label on these?** A: No ## Frequently Bought Together - UCGOU Poly Mailers 14.5x19 Inch Black 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 10x13 Inch Black 200 Pack Shipping Bags #4 Strong Mailing Envelopes Boutique Packaging Postal Self Seal Adhesive Waterproof and Tear Proof Small Business for Clothes Books - UCGOU Poly Mailers 12x15.5 Inch Black 100 Pack Medium Shipping Bags #5 Strong Thick Mailing Envelopes Self Sealing Adhesive Waterproof and Tear Proof Boutique Packaging Postal for Clothing --- ## 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.tw/products/260657085-ucgou-poly-mailers-14-5x19-inch-black-100-pack-large](https://www.desertcart.tw/products/260657085-ucgou-poly-mailers-14-5x19-inch-black-100-pack-large) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-04-22*
