Japanese Underwear - Hadajuban - Size L

I found this while organizing my dresser.
I believe it has been stored for a considerable amount of time.

I have not opened it to check the contents, but there is a faint yellowish stain-like mark near the right cuff.
There may be other stains or marks upon opening.
Therefore, I am listing it at a lower price.

For shipping, I will use recycled materials for simple packaging.

Thank you to anyone who understands the above. m(_ _)m
