Japanese Underwear - Set of 5

I received this from a kimono enthusiast and left it as is.
I rarely have opportunities to wear a kimono anymore,
and I couldn't bring myself to throw it away,
so I'm listing it for now.
It's crumpled. It has wrinkles. It also has stains. There's also a name written on it.
I wonder if it would be usable for practice if washed properly?? My frugal nature...

Whether it's usable or not? (I'm not confident it is)

I will pack it into a cardboard box and ship it.
The stains, wrinkles, and crumpled state are all as is.

Please only bid if you are willing to pay for shipping. <(_ _)>
I will try to fit it into a size 60 box, and if it doesn't fit, it will be size 80.

I tried packing it.
I'm going to force it in. I'll use size 60.
