It would be a shame to hide the One’s beautiful design under a bulky case just to avoid wear and tear. We've introduced our unique range of StyleSwap exchangeable back covers, so you can not only add a bit of a personality to your OnePlus One, but also easily swap out a dinged case without needing to replace the whole device. StyleSwap covers come in a range of materials and textures, including kevlar, bamboo and denim on top of standard silk and sandstone. Now you can customize your phone for the look and feel you prefer, and change it up whenever you'd like.

use hopshopgo.com ... shipped to US address and then use them to fwd to Malaysia (Int shipping fee USD25) or comgateway is the same also

I agreed with you bro. I also would recommend anyone here buy local if you don't have invite. Because I bought the International version 64GB already. Here reason why.

349$ (64GB OPO) + 12$ (Shipping Handling) + 25$ (Forwarding) = 386$ (aprox. RM1227)

In you are in bad luck.
RM1227 + SIRIM (RM100) = RM1327

Local OPO selling RM14XX. Just slightly RM100 more. Why such hassle to get International version where you don't even have invite? Somemore local importer offer 2 year AP warranty.

Got my OPO 64gb from DHL this morning. Total damage rm1360.. after sirim.

mine got yellow banding about 0.5 cm at the bottom... 
to anyone curious about sirim permit application.

I followed the guide found here.

https://forum.lowyat.net/topic/2637098

Make sure you have all documents.Just follow the checklist in the zip file

1. Copy of IC
2. Technical specification http://oneplus.net/one#specifications
3. Commercial invoice from courier ( call up courier to email you a copy)
4. Completed forms (for the tariff code, its 851712000)

Once done, they will email you the permit which you should forward to your courier.

There is absolutely no tax or duty on mobile phone import into Malaysia. Most is you pay rm100 for Sirim permit. If DHL handle your import be prepared to pay an exborbitant rm160 for their services - this figure reported to me by PM from a forumer here. If poslaju handle for you the service fee is around rm50+ only

You can avoid paying this rm162 by telling DHL you will apply sirim permit yourself n clear it at custom yourself. DHL charges is ridiculous

How do I get an invite?
The main method of getting invites will be through others. In the beginning, when not a lot of other people have the device, you'll be able to get invites through contest and raffles. We have planned ways so our early fans, as well as people who weren't here from the beginning will be able to obtain invites.

When do the next batch of invites roll out?
The first real batch of invites roll out late May, and will be of the 64GB Sandstone Black version. Any invites that you might have been promised before this, will be sent during this time.

How long are invites valid for?
For invites that you receive, they are typically valid for 24 hours. If they expire, they get returned to sender so someone else can get a chance to buy it. Alternatively, you can ask for the sender to resend it to you. For invites that you can give away, they are usually valid for longer, usually 1-2 weeks.

How many invites can I give away?
This varies. In the beginning, the quantities will be smaller, but increased as time goes by. You will frequently receive new invites to give away as production ramps up.

When do I receive invites to give away?
You do not automatically receive invites when you purchase a phone. We will need to manually roll them out according to our operations situation.
