Sin Chew Daily reported that there was an added "bonus" for customers who buy two panties each - they will receive a free video clip of the 19-year-old taking off the lingerie but her face was not shown.
It also said that she had sold 16 panties so far.
It was reported that the girl, known only as Felicia, started her sexual fetish business last month through her blog. About 200 people left their comments on her blog.
"All the panties will be worn by me for at least 12 hours before being sold," she said in her blog.
However, Felicia has refused to come forward for a personal interview and later decided to stop giving out the free video clips.
"I cannot reveal my identity and let others know who I am," the Star Online quoted her as saying. (ANI)
