I purchased this new, but it has been stored in a closet unopened since it arrived from the manufacturer. This is a set including two silica gel packets and the internal dividers. I believe the desiccator cost approximately 100,000 yen, the inner plate about 10,000 yen, and the silica gel a few thousand yen. With an inner diameter of 30cm, it can be used not only in laboratories but also for storing cameras and other items. Thank you.
