Seem to work the way they are supposed to. The strips are easy to tear off the book.

Very accurate, especially for my first time making my own soap. Any soap maker knows of the zap test and well according to the Zap test the strips proved accurate.

If you put it in the substance and it just looks like it’s wet and didn’t change color, that means the color is yellow. Came individually wrapped in plastic

Not sure if these work or not because the color doesn't match to any pH on their scale

It don't give you the level of numbers. It just gives you the color and you just gotta figure it out yourself that sucks

I purchased the strips to test ph in vinegar, I tested four homemade vinegars that all tested three percent, I was sceptical so I tested a store vinegar that was marked five percent and it came up three, I tested a second store vinegar that was supposed to be six percent and again came up three percent. Do NOT trust this product.
