【Lowest Price!!】 This is a new, unused item. We have a solution for these problems: * I want inexpensive products. * I want high-quality products. * I want to have a professional inspect my products. * I want to use it to practice for a practical examination at school. This product is a must-have for such people! This product is inspected by a care/rehabilitation professional, so you can use it with peace of mind. We have sold our products on e-commerce sites other than Mercari, and many caregivers, rehabilitation workers, and students have purchased our products. This product has been highly evaluated on all websites and has a proven track record. The products shown in the photos are all that is available. (This picture was taken at my home.) The package has been opened once to check the operation. It is also very useful for medical and nursing care related jobs! How about for medical students to practice? A stethoscope is included as an extra.
