I lives in Canada but I think I can see Avent milk bottles selliing everywhere. As far as I know, all the bottles that has BPA are recalled so the ones selling in the market are BPA free even these Avent ones. But I've used it with my daughter last time and I don't think it's good. Alot of ppl here recommanded a brand call BornFree.....I don't know if it's selling in HK tho.
