📝 Note for collectors
I didn't manage to find any pins being sold on Flea Market in Sham Shui Po neighborhood.

📍 HO唱片行
Very interesting shop which sells mostly various antiques and cool old things, not really a souvenir place - but it was the only place in Hong Kong I could find a pin from HK - with an old coat of arms.
