This ultrasonic cleaner effectively cleans glasses, jewelry, CDs, and DVDs. Although it's unused, it's old. I've confirmed its operation by inserting four AA batteries, which I've now removed. If you absolutely need the batteries, I can include them for an additional 300 yen, so please comment before purchasing. - Color: Blue and White - Type: Ultrasonic Cleaner - Uses: For cleaning glasses, jewelry, CDs, DVDs - Features: Includes cleaning brush Thank you for looking.
