Bringing Keris to Indonesia from Overseas
 

I will be travelling back to Indonesia (Yogyakarta) over the lebaran holiday and am thinking of bringing some krises back to Yogyakarta (to be left there) from Singapore.

I have read past threads on the topic (which was from several years ago), which advice to pack securely (sheathed, in checked-in luggage) and declare to custom upon arrival. Also general advice to be polite and patient. Is there any other specific procedures or precaution I should take? Or generally it would be better to use courier/logistic services (UPS? FedEx?)

For context, am Indonesian heritage and fluent bahasa speaker.

Thank you in advance
