Don't really know if I should ask that here or not but figured he could use it as a toy so I'll put it here. I'm sure it's been asked before but with a quick search I didn't find it. The brown paper that comes in the boxes with alot of the items you other online. Is it safe to use as a toy? Taking into account what it shipped with obviously, Like toys or pet food ok where as some type of chemical you don't want to use.
