Review on 📦 Waterproof Tear Proof Expandable Polyethylene Envelopes: Optimal Packaging & Shipping Supplies by Rui Adams

I purchased these mailers hoping they'd protect my items, but they're not worth it. Thanks to my knowledge gained in practice, I know that these 'waterproof' and 'tear proof' polyethylene mailers can still be damaged in transit. The only pro is that they're expandable. The cons are the false advertising and lack of actual protection. Don't waste your money.
