The Healthy Wiser PH health strips for is as described on the product description page
https://www.amazon.com/gp/product/B00PI6SNKA. People use testing strips for all sort of reasons. I try to maintain an alkaline body and test often for PH. These strips are convenient to use for the first morning urine or for saliva testing. There are two strips to read and then take an average of the two for your total PH number. I try to keep mine around 7. The acid/PH test I took this week my numbers were 6.5 on the top read and 8.0 on the bottom for an average of 7.25. No diet changes needed this week. Comes in a nice little plastic box.
