I received my order very quickly, that was nice. Strips work great,I neglected to research these in detail the strips do not offer reading for in between,such as 7 1/2. Still satisfied with my purchase

used this to test ph in soap did not work

These are awesome verses the more expensive ones. Plus they have the whole PH scale. I definitely will buy again.

These Litmus strips are pretty easy to use. I make cold process soap and they have been really helpful just so that I can have reassurance that the product I'm making is safe. I would give this a 5 but am giving it a 4 because the strips are pretty thin and can be kind of difficult to separate. Also, the little strips are pretty thin--almost like tissue paper but a little thicker. Basically don't expect to get a strip that will stand on it's own. I found the best way to use them is to put the liquid you are testing in a shallow dish and then lay the strip across the liquid. BUT they can be dipped--I just think it's easier the other way.

Very happy with my product, super fast shipping.

In learning to make soap, I want to make sure my soap is well under any acidic levels. I want a mild soap.
