No...
But seriously, boxwave started shipping "soft cards (to work bubbles out in application)" and cleaning cloths with their screen protectors as of late.
I wrote to ask if I could get a few, considering that I had bought 5 protectors before they started shipping these additional items, and they replied, "sorry...we don't have those separate."
That disappointed me. They should have dropped a few in the mail...they can track my purchase record.
And they should ship them free...great
PR. "Boxwave" is right on the cloth.
