This is a set of deodorizing and antibacterial chips for the Nyan-tomo Clean Toilet. I had some in stock, but my cat's preferences changed, so I'm selling the unopened items. These are cat toilet chips specifically designed for system toilets, and are better at eliminating the odor of feces and urine than regular chips. ■ Deodorizing Professional Small Granules 4.4L x 2 bags ■ Ultra-Kaidio Premium Small Granules 4.4L x 4 bags Total of 6 bags. ※ These are renewed products, but the contents are the same. See the images. I will pack them in a cardboard box and ship them. Thank you.
