This is Takao Katano's "Jindai Moji Healing Power Automatic Charging Sheet." There is a faint small color under the character "南" (South) on the white sheet. Please refer to the second image. Also, the vinyl has wrinkles at present. The back sides of images ② and ③ are images ④ and ⑤. The vinyl smell that I was concerned about at the time of purchase has disappeared. Please purchase only if you understand the above. ☆ Quoted and modified from the HP below In the shape of a triangle, energy flows from the base to the apex. In the human body, the sacrum and the shoulder blades on both sides form a triangle, taking in energy from the air. This sheet enhances the power to draw in and absorb aerial energy by having spells (Hifumi Norito, Awa Uta) written in a spiral shape using Jindai Moji (Hotuma characters, Homemi characters) within the triangle. Since it will take in energy from the air, it can be used for a wide variety of purposes, but first, it is recommended to use it when you can't sleep, when you are tired, or when you want to adjust the distortion of your body. How to use: Place the sheet under the floor or futon and sleep on it. Size: Length of one side of the triangle = 27 cm
