Rugby World Cup 2019 officials are calling a foul on volunteers who are hawking their official uniforms including polo shirts and caps through flea market apps and online auction sites.

The organizing committee said although no cases have been confirmed of the clothing being used for wrongdoing, it is calling on volunteers to abide by the agreement they signed not to sell or give the gear away.

Still, listings on a flea market site pitch, “This is a set for the Rugby World Cup! It is not sold commercially” and “I used it about twice, but it is in near-mint condition.”

Ads listing a polo shirt, cap, bag and other items are being sold for an asking price of about 80,000 yen ($735). One ad had a Rugby World Cup windbreaker that sold for 23,000 yen.

Right after the start of the World Cup, there were ads posted on Internet sites seeking to sell the outfits given to the volunteers.

The organizing committee recruited about 13,000 volunteers for the World Cup and gave them items including windbreakers, polo shirts, pants, caps and water bottles.

When handed their uniforms, volunteers were required to sign papers promising not to give them to a third party or sell them. During their training sessions, they were also given similar instructions.

However, the committee has confirmed that goods from volunteers are being offered through Internet sites, such as leading flea market app Mercari, operated by Mercari Inc., and the online auction site operated by Yahoo Japan Corp.

Committee officials have asked those operators to prohibit users from selling the goods and is continuing to have discussions with them.

According to a woman who volunteered in the Kanto region, there were volunteers who didn’t show up even once after agreeing to help out. Among the World Cup volunteers, there are many who have also volunteered for similar duties for the 2020 Tokyo Olympics.

“I think that there are members who applied (to be World Cup volunteers) to get those items," the woman said. "The same thing will happen at the Olympics.”
