Mine are ph strips they were included with a human integrator powder that shoul decrease human body acidity. They are dark yellow. I said yes for litmus strpis because i googled and the picture i saw was similar... Sorry for confusion! As for distilled water it seem it does not have a neutral ph too, at least according to an article i just found. But I'm about to go to a garden center and see if i can find something affordable to test ph. Many thanks for all the help!
