OK first of all these were literally just stained before they went in the box. The box is leaking stain from it and smells bad. I open it and the paper wrap inside is covered in stain. 
Second, the wood is all one color, a grey stain, not at all like the picture with the shelf looking like a different wood or a different color. 
I will return. 
How long must I wait to use them? Do I wipe off all the stain that is running everywhere? 
What a Disappointment!
