pH Test Strips on Vinyl Wand with Range 1.0 to 14.0 (50 per Pack)

I'm using these strips to try and test in the 3.5 - 5 range. We can tell if something is much higher or much lower, but it's really hard for us (us being 3 sets of eyes, ranging from 21 years old to 63 years old) to distinguish matches from the wand to the chart in that range. But at least we know we're in the general ball-park, and at least the strips test down below 5 (in theory). Very easy to use.

Just what my daughter was looking for in her soap making business......thanks Amazon!!!!
