DOESNT SPRAY do not buy
Style: Kids SPF 50, Size: 5 Fl Oz (Pack of 1)
Doesn’t work AT ALL. And I’m annoyed because it’s not eligible for return even with prime. What am I supposed to do with a sunscreen that won’t spray? YES, it’s in thru blocked position, it will not spray. I’d love my money back please.
