Humid and hot environments are the enemy of camera lenses. Disassembling and cleaning lenses takes time, effort, and money. By periodically heating the dry stone in a microwave (to remove absorbed moisture), it can be used semi-permanently. Recommended for those who want to store expensive lenses in a portable form. The original price is 3980 yen. I had planned to use it, but it remained unopened, so I am offering it to anyone who needs it. #Dehumidifier #CameraAccessories #Desiccant
