IRIS OHYAMA Pet Drive Seat I received this from a friend several years ago. I have never opened it since receiving it, and it has been stored in a dark place. The frequency of use is unknown, but my friend (a dachshund) used it. There is no hair, etc., and it looks relatively clean. The instruction manual has wrinkles and some tears. The bag has dirt on the adhesive part, etc. Contains silica gel There may be a slight odor, although it's unclear if it's from the original product or the silica gel.
