Dont actually have the item in front of me, but my wife remembers a faint water-type stain on the back before I cleaned it.
I cant tell if its still there or not, but take a look at the pictures...  Looks fairly clean, and i will double check before sending!
Mostly hidden in the back if so anyways.

Take a Look at the Pictures for more Details - 
And Message Me with absolutely Any Questions!

Thanks!
