In Bangkok? looking to get a few for a party but cannot find. Don't want the crappy firecracker type you see at Chinese new year, few rockets and roman candles that sort of thing

Careful! Thought they only sell em on special occasions like songkran etc.

There's an area near golden mountain ( a temple in Bangkok ) where they make and sell all sorts of fire works they are displayed in the open and anyone can buy them .

interesting thanks will look there
