I have never seen one in Pinas store shelves in my life... if meron man, for sure mga PX good stores lang meron, maybe duty free has it, I don't know... But take note, there are copy-cat versions available sa mga tool stores, most of them don't contain any paraffin wax or if meron man, it's something else.
Original cali dusters are made of pure cotton strands baked in paraffin wax coatings.. they're perfectly safe and will last a decade or so with proper care...
