Moving to HK from Oregon, US (Hong Kong)

We are packing our container in the US soon, and since we are experienced expats, we know that there are always those specific things that you can't get everywhere. (Ziplock bags or king size/comfortable bedding, American cereal, etc.)

Would love advice from other expats on the things that they wish they had packed a case or two of! (We have twin 8 year old girls)

Thanks for any other nuggets of advice for our transition - very appreciated!
