This is a device that effectively cleans contact lenses using ultrasonic waves. I no longer need it because I've started buying 1-day lenses. It's unopened and brand new. This is an excellent device that cleans contact lenses with ultrasonic waves. The cleaning time is 3 minutes. Recommended for those who use colored contacts or during the pollen season. - Type: Ultrasonic contact lens cleaner - Size: 67mm x 60mm x 30mm - Weight: 66g Thank you for looking. #ContactLenses #Contacts #Cleaning #EyeglassCase #Eyeglasses #Sunglasses #EyeglassCloth
