Universal pH Litmus Paper Roll 0 - 14 (5 meter)

5 out of 5 stars Friday 27 January, 2017 By Julie Freeman
Does exactly what it says on the website. I'd looked at other options that were available and although there were definitely cheaper options, the reviews were not optimistic. I bought this one hoping it would work and it showed instant results, displaying exactly what I was expecting. 5 out of 5, would definitely buy again.
