Durex seems to be the brand of choice, available in the pharmacies and 7-11 stores. Generally, I've brought my own Sagami or Okamoto condoms from HK (
Sampson Store on Nathan Road to be precise). Sagami ones are fun because the girls usually have never seen condoms in the peel-the-top-off packaging. I love the momentary puzzled look.
