A great lube from one of Japan's leading adult brands, the Toy's Heart Lotion Hard Type Lubricant is versatile and a joy to use if you like thick, viscous lubrication. The lube contains a unique blend of the Thai and Laotian natural herb Kaempferia parviflora (Krachaidum), which is even more performance-enhancing than maca and longjack (tongkat ali), and with twice the amount of arginine.
