Toshiba Deodorizer Airion Slim DC-230 (W) Small Deodorizer x 2 Accessories: Wall mounting hooks x 2, wood screws x 4 Deodorizing gel containers x 2 (empty) * Refill gel is not included. * 8 AA batteries (4 each) are required to operate the two units, but batteries are not included. Purchased from Amazon in April 2016 and used indoors, but I stopped using them because refilling the deodorizing gel became a hassle, and they were stored at home for a considerable number of years. Due to the passage of time, there are many instances of yellowing and minor scratches on the main units. One of the battery holders has rust due to battery leakage (photos 8 and 9), but I confirmed their operation before listing them, and both units are working (photos 12 and 13). The included blue-labeled containers are empty, but I will include them as they are necessary for those who purchase refill gel. Please understand that these are used items that have been in use for a considerable number of years before purchasing. We will use recycled cardboard for shipping, and the empty containers will be stored inside the main units for shipping (photo 14).
