what kind of saline spray do i use?

this is probably a ridiculous question, but this is my first piercing and i already messed up by getting bactine instead bcs my friend said it would be fine😭 and i dont have a lot of money to get the really good stuff, so i’m looking online (just searched saline spray) at the dollar store and both of these seem alright to me but i want opinions from more experienced people :,)
