Inaccurate product description. Why show red litmus paper in pictures when you only want to send blue. The blue litmus paper I received works fine. Two starts due to false advertising. I'm wondering how tall and clear the red evil stands (which you don't get on this product), the blue lying on its side is the only thing you'll get. I know I could have read the description, I guess I couldn't think of any reason why I would take the red one too because it looked me in the eye
