Used, in good condition. Functionality has been confirmed. Requires 3 AA batteries. (Batteries not included) It's clean with no noticeable stains, but if you are at all concerned or seeking a brand-new, perfect item, please refrain from purchasing. This is a wired speaker with a built-in amplifier that connects to smartphones, etc. The speaker itself does not have a volume control knob, so please connect it to a device that allows volume control on the sending side.
