Hi noel,
I've been to a couple of hobby shops in HK tow years ago. Please find the ff:
UML - Universal Models. 311 Glouchester Rd, Causeway Bay
www.hobby@universal-models.com
They have a huge, i mean "HUGE" range of models and accesories.
Chong Fung Co. - G/F, No. 10, Kwong Wah St., Mong Kok, Kowloon
They sells verlindin models and lots of magazines.
P.S, Hope this helps. BTW, I'm not sure if both are still there since it was 2 years ago since I been there. Also, there's a road in Mong kok that have a lot of stores selling models and airsoft and I think its the one whre Chong Fung is located.
