Aulos 309A Brown Case for Alto Recorder, made of synthetic leather for durability. - Brand: Aulos - Model: 309A - Type: Case for Alto Recorder - Color: Brown - Material: Synthetic Leather Thank you for viewing. This is an alto recorder I purchased about 8 years ago. I bought it in a hurry because I lost my other one, but I found the original one soon after, so I hardly used this one. (Used for 1 month, only once a week for music class) Of course, it has been fully disinfected.
