pH Paper Pkg. Of 100

Product Review (submitted on October 2, 2009):

The first pack of these that we received did not work. They got wet, but did not change color. We contacted ES and they sent us a replacement pack which worked great! Would be nice if they came with some instructions and/or other information, but between the provided color chart and the internet we made do.
