## Questions & Answers

**Q: Are these recycable?**
A: Not Eco-Friendly! These are 100% virgin plastic, so not good to start with. No recycled materials were used to make these (shame), and no, you can't recycle them because poly packaging is generally rejected by recyclers.

**Q: how many mailers does it come with? like how many bags are there.**
A: I ordered 100 pcs pack, they should have other quantity pack if you do not need 100 pcs or need more than 100 pcs.

**Q: How many ? It doesn’t say.**
A: Hi , 1 Package of 100pcs

**Q: Would these bags be suitable to ship a pair of adult shoes , no box ?**
A: You could ship shoes in this, I think it wouldnt rip.  If it is for a customer, I would use a box instead or a bubble wrapper.

### ⭐⭐⭐⭐⭐ Review
*by M***K on 14 July 2025*

This is probably the 3rd time buying these. They are perfect for shipping clothing if you use Poshmark, or some other reselling site.. I can fit a few shirts, and even a Pair of Jeans very easily. I typically add a strip of packaging tape, to ensure it is fully sealed, but I think that might be overkill.
