Petio One-Hand Easy Dog Trainer Brown Regular for Dogs & (Petio) Easy Care Dog Trainer Sheet Tear Prevention Cover Brown for Dogs This is a set of Petio's toilet trainer and sheet tear prevention cover. I purchased and opened it, but I didn't have a chance to use it, and it has been stored for about half a year, so I am selling it. I have cleaned it simply for the sale. I would appreciate it if you could understand that it has been opened. I will pack it with air cushions and ship it.
