Sending a package to Brunei

I'm planning to sent a package to Brunei from the united kingdom sometime soon and have a few questions.

1. Is the postal service in Brunei reliable and secure?
2. Are their any customs fees or handling fees that might need to be paid on delivery? (Will declare the package as a gift)
3. How much did someone paid to sent a package to you from the UK or the EU?
4. How long did the package take to arrive?
5. Anything I shouldn't sent?
Thanks

I sent a document via courier over Christmas and cost me around £20 UK pounds. It's still on route. I was advised not to send via normal post. If a parcel (goods) I believe you will need to complete certain paperwork and declare items but the courier service will best advise. We used TNT

Hi,

Based on my personal experience, best not to use normal postal svc.
At least register post or courier highly recommended.
No religious articles for sure. They screen through every parcel.
