What is the purpose these items?

At first I thought the needles and the bottles were opium related items, but now I don't think so. The little purse opens and the weight is marked.

 

Probably lime containers.

The "little purse" is probably a Tibetan fire starter kit. The pouch would be for holding the flint, and the iron striker is the curved part along the bottom edge.

 

Lime interesting...No idea why the photos repeated themselves. I will try and edit.

 

Exactly what they are. I have one too, although I am trying to limit my betel related items to Indonesia.

That's right as well, I have a few, one of them still has a piece of flint.

 

Authentic or tourist repos?

 

all look genuine and the fire starter had all it parts so....it's kicker !!!!

 

All authentic. The lime containers could be from Laos.

 

Are those hair pins or some sort of skewer ? Chinese ?

 

hairpins that doubled as defensive weapons when called for !!

 

Madurese women wore small kerises in their hair for the same reason.
They were often alone for long periods of time, while the men made a living in maritime trade. Many women were traders (on land), so they met all sorts. An extra keris comes in handy sometimes.
