Change your image of liquid chalk with its grip and durability
PD9's ingredients are different from regular liquid chalk. The secret is its main component, alumina, which is a fine metal particle. This alumina absorbs sweat and moisture, creating a strong grip. Alumina is used in abrasives and medical applications, and safety tests have confirmed that it has no adverse effects on the human body. It also contains emulsion and citric acid to prevent dryness of the skin. It penetrates deeply while gently protecting your fingertips.
