Playtex Sport Tampons, Super Plus Absorbency, Unscented - 36 Count (Pack of 3)

If this should be 2 packs of 18 each for a total of 36 tampons, why are some people only receiving 1 box of 18?

Are the applicators and wrappers flushable? Has anyone successfully flushed them down the toilet?

Is this 2 boxes of 18 or 2 boxes of 36?

will they leak if you go swimming?
