How to sell panties

[FrenchySwingerCouple]

Hi,
I heard that I can sell my panties in yahoo auctions website, and that it's really good to earn money here in Japan. ( I already have done it in France before)
But the thing is that here there is a technical way to do it.... I heard that girls put a special keyword because in Japanese Kanji (that I don't know which one is) it's a meaning of something like a shelving unit...
Could you help me?
Thanks a lot

ブルマー ?

ブルマー ?

The results are not what I expected...
May be add Used... In Japanese
But I really think there is a cheat keyword for that

You can try ナマセラ ブルマー
Or you can go to a sex shop with burucela section and see the keywords or ask to the staff how to sell it.
