Four major Japanese department store operators said Wednesday they will provide refunds for bracelets they sold as products of a popular U.S. brand that are now suspected to be fake.

The operators said about 200 bracelets were likely sold under the Chan Luu brand for ¥8,000 to ¥30,000 each at eight outlets of their Seibu, Matsuzakaya, Daimaru, Keio and Isetan department store chains.

Sogo & Seibu Co., Daimaru Matsuzakaya Department Stores Co., Isetan Mitsukoshi Holdings Ltd. and Keio Department Store Co. said they will refund payments at customers' request.

A company that opened stalls at event halls during accessory sales events by the stores in Tokyo and its vicinity, and in Osaka and Nagoya, sold the products in question, they said.

"Detailed circumstances are not known since the event hall sales were managed by an outside trader," the department store operators said, while recognizing their own liability.

The brand operator, Chan Luu Inc., said it has been asking the department store operators to investigate.
