## Questions & Answers

**Q: Hola quisiera saber cuáles son las medidas ya que en el título dice una y en la imagen y descripción viene Otra, cuál es la correcta ?**
A: Hi, the size of this poly mailer is 14.5x19 inches.

**Q: Can anyone tell me if these would be good to ship heavy books? 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
