G PROJECT has calculated the internal structure and the golden ratio of lubricant and air, greatly enhancing the user experience! The outer layer is made of the next-generation artificial skin material "ARGON," which subverts conventional knowledge and recreates a new material that is soft but not sticky, with a refreshing feel like human skin. The inner layer uses the revolutionary material "momochi," which becomes more adherent to the user's body with use, like a new material with the same elasticity as real skin. Please enjoy the sensation of rubbing against a material with extreme softness and hardness, which will provide a feeling of real sexual intercourse! WARNING: Keep the product away from children.
