Nowadays, you can get lots of custom jewelry, hair assessories/ decorations, earrings, bangles, etc from the night market (pasar malam) sold at a reasonable price:
Choices are quite good- whether they last or not, that’s another question.
The vendor is also smart to use the kind of lighting that give the goods a more ‘appealing’ look. Some of the items would have cost quite a lot years ago. But as the items have flooded the market now, the price can be lowered. When buying, just buy for fun- as most of the time, these items would not last for very long.
