I used this item for about three months, and then kept it at home for about a year without using it. The nylon part of the nylon inner pocket inside the bag is slightly dirty. See the third photo. Other than that, I think it's relatively clean, but there may be oversights, so please refrain from purchasing if you are very particular. Instant purchase is okay.
