Digital BW, The Print

Hi All,

I've never shipped prints before, and am leery of rolling them. I saw a reference to these 
Print Pad thingies a short time ago...is this the best way to go? Lined or unlined?

And if anyone has any other shipping recommendations I'd be thrilled to hear them. I'm 
shipping 3 photographs printed on HPR, 11x17. I'm terrified they will scratch or flake 
during shipping. Suggestions?

Thanks,
Sarah
