Review on 🧪 ColorpHast 9590 pH Test Strips 0-14 by Nathan Jones

As an esthetics instructor I was looking for inexpensive pH 0-14 test strips to use in the classroom. At 12 cents a strip it was a great bargain. The value was even better once I started using them. The pH of the products we apply to our skin is very important. Sometimes we want to raise or lower the pH, but we also want to make sure we follow this rule with the right product to then neutralize the skin's pH. Using these strips is a great visual aid and makes learning (for me and understanding for her) much more effective. I've used them on many products that I already knew the pH of and they were accurate every time. The no bleed factor is also good as I feel comfortable dipping the strips directly into my product. So far this product has not let me down. I will definitely stick with this product if I order again.
