Foot Reflexology Mat Long Type Total Length: 170cm * Stimulates the foot's pressure points simply by walking or stepping on the mat. * The stone-shaped protrusions are easily removable, allowing you to adjust the quantity to your preference. * I haven't used it much, so I think it's clean, but I will clean it with alcohol disinfectant. * How about using it for a penalty game at a year-end or New Year's party? It might be fun! For those who understand that this is a used item, thank you for your consideration. m(_ _)m
