Used only 10%. Weightlifting, tennis, golf, baseball, gymnastics, etc. 【Powerful Grip】In sports where "grip = hold" is crucial, such as golf and tennis, the fear of your hands slipping is always present. PD9 was developed to solve the problem of sweaty hands and provide athletes with peace of mind. 【No Whitening】Using anti-slip products often leaves hands white, but PD9 is a transparent liquid chalk, so there's no need to worry about white powder. It does not use rosin (pine resin) or magnesium, which are often prohibited in gyms and are the cause of white powder. 【Optimal Size for Portability】PD9 is designed to be easily used with one hand and fits easily into bags and pockets. Unlike spray or powdered anti-slip products, it's easy to carry and use in any situation. 【Contents】1 bottle 60ml, approximately 200 uses. Refill 300ml, approximately 1,000 uses. PD9 provides approximately 200 uses per bottle, making it highly cost-effective compared to conventional powder or liquid chalk. (The number of uses may vary depending on the season and individual.) 【Country of Origin】Japan. Made in Japan and uses skin-friendly ingredients, ensuring quality that can be used with confidence in various sports. It contains no harmful ingredients to the human body, so it can be used safely by children.
