Thank you for viewing. I purchased this for a class, but I only used it a few times, so it's in good condition. There are no noticeable teeth marks or stains. It has been sterilized by boiling before listing. The case has been stored at school and home, so it shows some signs of use. It has been soaked in Oxiclean, hand-washed, and air-dried. I think you will be able to use it comfortably. 【YAMAHA Alto Recorder YRA-28B Ⅲ】 A cream-colored alto recorder made by YAMAHA, with cleaning tools, and featuring a B-flat tone. - Brand: YAMAHA - Model: Alto Recorder / Baroque Recorder / YRA-28B Ⅲ - Color: Cream - Accessories: Case, cleaning tools - Cleaning tools: Cleaning rod - Key: B-flat
