pH Test Strips 4.5 - 9.0 (100 strips) for Urine & Saliva

5 out of 5 stars Tuesday 02 February, 2016 By Ajp79
I really love these Simplex Health pH Test Strips. They offer an easy way to check my acidity levels. Simplex is a brand I trust for these test strips. I"m a happy customer so 5 stars from me and I'll certainly be reordering more.
