For this hell note thing. For offering to the ancestors. The normal paper gold ingot thing is fine. All those other commercial rubbish is just to enrich the merchants peddling that crap. Paper Houses, cars, headphone etc is just for show. As if the after life need this sort of stuff. Offerings to ancestors is to remember them and honour them. Even in ah tiong land. The tiongs dont go over board the way singkies do.
