[Size] Approximately 60 cm x 25 cm (when open) This is a compact xylophone that I have kept at home. It's foldable, and when you open the green box, the xylophone is set up as shown in the photo. My child used it when they were in kindergarten, and there are tape marks and minor scratches on the keys, but the sound is clear and the keys are relatively clean. The wooden sticks of the mallets are soft and worn down from being used. Please check the photos. This is a used item, so please refrain from purchasing if you are concerned.
