| You can get the disposable ones in Po Lam (one stop on the MTR from Hang Hau) at the City Store (think that's the name). It's the big department store at the end above Park and Shop.
It's a bit out of the way but if you can make it out to Razor Hill in Clearwater Bay, Dr Henderson at OT&P is an excellent Dr. Tel 2719 6366 |
