I hesitated to purchase this product because of bad reviews stating that paper turns green in humid climates. I am a taxidermist and need to test my tanning solution to see if it is good for grooming. At first I was pissed, I live in Florida and of course the whole reel came in green. But the stripes still work. I dipped the strip in milk and it showed a value of 7. Then I dipped the strip in the acid I use to stir the brine for the skins and it immediately turned bright red, meaning "0". Overall, I'm very happy that these strips still work. I will store them in a ziplock bag with some rice for added moisture protection, but otherwise this product works well.
