This is a set of the original hybrid wax Kurosen (Black Flash), which contains high-purity fine-particle graphite and surfactant, and a high-surfactant interface WAX. Made with domestic paraffin. This wax was developed after seeking a wax that is easy to apply and works in all snow conditions. After repeated impressions from myself and my friends, and numerous trials and errors, we finally arrived at a satisfactory wax formulation. ● Recommended for those who: ・Don't want to wax repeatedly but dislike poor board glide. ・Want to save time on hot waxing. ● No base wax needed Highly penetrative, it serves both as a base and top coat. You can enjoy stress-free gliding for up to 7 days with a single application. Durability is further enhanced when applied over base wax. Due to its high penetration, there's no need to wait for it to cool down after hot waxing; immediately scrape and brush. Can also be used as a rub-on wax! ● Compatible with all snow conditions from -14°C to 11°C Glide smoothly without stress in any condition. ● Effects of Graphite Suppresses friction heat and static electricity. Quickly dissipates heat and reduces heat spots, preventing wax depletion and prolonging the wax's effectiveness. Reduces the coefficient of friction and improves abrasion resistance. Japan is an island nation surrounded by the sea, so even fresh snow in the high season contains salt. Friction occurs when salt is mixed with snow. Especially in spring, impurities such as pollen and PM2.5 are abundant in the snow, causing friction and static electricity. That's why we believe graphite, which suppresses friction and static electricity, is essential for Japanese snow, regardless of the season. ● What is a Surfactant? Simply put, it's a substance that connects water and oil. It has the effect of lowering surface tension, resulting in: High residue and high penetration. Significantly improves wax durability. Reduces water resistance and friction, which cause speed loss.
