Military BDU set for airsoft, with belt (3B)

Camouflage combat uniform for airsoft, top and bottom (with belt).
It has a mottled camouflage pattern that seems to blend well with Japanese vegetation.
The material is 69% vinylon, 30% cotton, and 1% other.
It's made of a fabric called "ripstop" with a grid pattern.
It has faded very nicely (I'm not sure what that means exactly).
There are also some areas that have a sheen from ironing, which makes me imagine that someone ironed it frequently.
Upon inspection, there were no tears, holes, or missing buttons.
Of course, please assume there are fold wrinkles, minor scratches, and abrasions.
There are also some faint stains, such as black stains that look like shoe polish, and stains that didn't come out in the wash.
I don't know much about the size, but both the top and bottom have the cryptic symbol "3B".
The pants have buttons instead of a zipper, which is inconvenient when urinating.
I still think zippers are more convenient for pants.
Please bid only if you can understand the item based on the images and this description.
