A swathe of the city's young confirmed their reputation for being among the world's keenest collectors yesterday as they queued in the hope of securing a limited-edition $599 camel-flap cap from Japanese clothing label Bathing Ape. The Queen's Road Central store opened at 11am and all 90 caps were sold in an hour. 'The caps are very cool,' store supervisor Jerry said. 'Many people missed out.' A survey last month found almost half the city's population are addicted to collectables.
