This Sofiamari Mini Traveler accordion appears to be in good used condition.

It has 8 base buttons and 22 treble keys.

I do not play accordion, but was able to test it to make sure that all the keys play.

The top row of base keys play octaves in F, C, G, and D, and the bottom bow of base keys play their corresponding chords.

All of the keys play, although I am not very proficient at working the billows to get a good, stable airflow.  It seemed that the A key was a little weaker than the others at times, but I'm not sure if it was my amateur playing or not!

There are a few scuffs on the body, but overall it is in nice condition.

The backpack case is in good used condition. It protects the accordion well.  The only thing I notice is that one of the zipper pulls on the outside pocket is broken, but the other one works fine, so it doesn't really affect the case's function.

Please look at the pictures and feel free to contact me with any questions.  Have a wonderful day and thanks for looking!
