This is a deodorizing sheet for the bottom of a trash can from Toyoda Kako. I repurchased this product because I liked how it worked, but I've switched to a lifestyle where I hang the trash bag, so I haven't used it at all, and I'm selling it. It's unused and unopened. However, I purchased this over a year ago. This is a relatively expensive product compared to similar items, but I'm offering it at a lower price for the reasons mentioned above. Thank you.
