A method of directly bonding two pieces of leather without the use of inner materials is employed, resulting in high durability and robustness. While it may feel somewhat stiff when first used, it will soften with a few uses, providing a comfortable feel. Additionally, tactile and auditory feedback (the sound of the leather compressing, "squeak, squeak") is provided when the switch is turned on and off. Accessories: Box Material: Genuine Leather
