50 Bagtron #6 Poly Mailer Bags 14-1/2" x 19" Shipping Envelopes Grey 2mil

I bought these envelopes to return clothing purchased online. They are as good as soft packaging you receive in the mail. The adhesive is also just as good. When you seal the envelope, it stays sealed. You could use these to mail hard, slightly heavy items, but you should pad them. They arrived when Gorilla said they would. The only thing I would change is that I would have bought the pack of 500. With shipping and tax, they would have cost me about $50, whereas I paid $28 for 100 here. It's a much better deal. I paid $10 shipping, whereas I would have paid $16 for 500. I would buy these again.
