Improper Use of Was, I think.

Burusera shops in Japan sell used girl panties. "Buru" means bloomers and "sera" means sailor, the sailor uniforms that are worn by Japanese schoolgirls. They also sell other types of clothes, such as school uniforms, blazer school uniform, school swim suit uniform, etc. The clothes are often accompanied by genuine photos of the girls wearing them. The clients are Japanese men that smell or otherwise experience the panties for sexual stimulation. In the past there were vending machines selling packaged used panties.

Namasera is a variation of Burusera. "Nama" means Fresh. The concept is the same as burusera, but the "goods" are still being worn by the girl who then removes them and hands them over directly at the point of sale.

The price for a pair of panties can be as high as 5,000-10,000 yen (50-100 US dollars).

Underage schoolgirls participate in sale of their used panties, either through burusera shops or using mobile phone sites to sell directly to clients. When laws banning the purchase of used underwear from under-18s were introduced in Tokyo in 2004, it was reported that some underage girls (called kagaseya or sniffers) were instead allowing their clients to sniff their panties from directly between their legs. Others chose to sell photos of themselves, throwing in the used panties for free.[1]

The panty fetish is not unique to Japan, but only there was it institutionalised to such degree.
