This is a YAMAHA tabletop xylophone. The model number isn't written on the instrument itself, but it's likely a TX-6, a discontinued YAMAHA tabletop xylophone. The manufacturer's suggested retail price was 17,000 yen. I've researched the model number and believe it's correct, but please refer to the photos and make your own judgment. There are signs of use, such as strike marks, but there is no significant damage. Some parts of the felt on the bottom are thin. Please check the photos. Mallets are not included. Please research the dimensions online. Everything in the photos is included. The item will be packaged with bubble wrap and cardboard (not the original box for this product) for shipping. Please refrain from purchasing if you are concerned about storage or shipping by a private seller. The price reflects the fact that this item is discontinued, the felt on the bottom is partially thin, and mallets are not included. Thank you for your understanding.
