This is an "Ele SaX," an electronic toy instrument in the shape of a saxophone, manufactured in the 1990s. It can be enjoyed as a display piece, interior decoration, or retro item. The company that originally released it is no longer in business, making this a very valuable retro toy. It is a rare, unused item with its original box, and is not widely available. This item is suitable for collectors and is expected to increase in value in the future.
