Spoontiques 13238 Live Laugh Love Stepping Stones, Multicolored

Are these intended for stepping on or not stepping on? if i was to go by the name, "stepping stones", is it correct?

Do I have to spray these stones with any coating before putting them in my garden?

How many stepping stones comes in this order?

I'm a bit confused - one person said one stone comes per order, another said two. Is the price for one or two stones?? Which is correct?
