■ High grip wet condition... GRASP original egg shell formula, egg shell powder dispersion effect and porous structure promote the absorption of hand sweat and moisture, making this chalk ideal for when your hands are sweaty during summer or when holding or rocks are damp. ■ What is GRASP... GRASP started with the goal of making chalk that climbers can most trusted. We poured our know-how to make our products in Japan with anti-slip material for sports and share the knowledge and experience of the worlds top climber Daisho Oyamada, and the senses we cultivated to date and started in early 2017. We repeat the many materials and formulas you can imagine, and have more than hundreds of prototypes and explore all potential and have gone through about a year of prototyping, the high-performance chalk "GRASP" has been completed. The challenge of GRASP continues to come. ■ Introduction of Magnesium Carbonate included in the product... High-purity magnesium as the basics of grasp chalk, is a safe and safe six-hydride (strict base) magnesium carbonated for food use using trace amounts of magnesium found in the clean salt water in the Seto Inshore Sea. It is also used as a food magnesium strengthener and a soft drink source, so it is gentle on the skin and safe for women and children.
