I used this underwater waterproof light for diving. I used it once or twice about 10 years ago. I washed and stored it after use. I checked it after a long time, and it doesn't seem to have any scratches or stains, but I don't know where to put the batteries, so I haven't checked if it lights up. I would consider it a junk item. It also has a case, but I may not be able to include it depending on how it's shipped.
