Most of them are up for sale, prices are up for discussion. So far she sold this one for $30.00 but I don't know other prices. And shipping to US would be $5.00.
Loi-San also is taking orders on either copies of her works or something by your wishes.
Best way to reach her is to PM me here. Loi-San doesn't have regular internet access so it would be faster. Her e-mail is loi-san(a)mail.ru
