There are no noticeable scratches or stains. The item's operation has been confirmed before listing. I used this for a while to easily clean glasses, lenses, etc. I haven't used it recently, so I'm selling it at a low price. Please note that you shouldn't have excessive expectations for the ultrasonic cleaner. For stubborn dirt, it's more reliable to wash by hand. - Model Name: SWT710 - Brand Name: CITIZEN - Material: Stainless Steel - Function: Ultrasonic Cleaning - Included Accessories: AC cable, basket, lid, instruction manual Thank you for viewing.
