describes the material offered here is very favorable in acquisition and prevents breakage when sending glass, ceramics and porcelain. it is nice and thick, well portioned and ruckzuck is also a shipping bag built. I take Anglo glue, cut a piece of deal to me, sticking together and you've got a great mailer that can protect almost everything will make post-ruined (nonsense, they do not do on purpose!) good to handle, prima thick and perfectly adequate to send to even more valuable things. I use plus the packaging chips offered on Amazon that are inexpensive and supi. full recommendation to buy, thank you.
