he LED has very good quality, the strip is cover by transparent rubber cabling. So it is safe to bend. You can take a look on the picture in below links
[attachmentid=4001614][attachmentid=4001619]

The length can only be selling in meter. No 3.5 meter, coz the led is 1 meter per strip.
I afraid if i take the whole length route for my detolf would be too bright, so i only take to route diagonally and it seems not bad. Detolf is well design to easily route the led strip using cable tie

Noted that the price when i bought should be different, depend on the taobao seller having any promotion or not.

While for taobao i am buyingvia my friend running electronic project business, he is selling taobao stuff for side business
Do contact him via emi if you interested.
Name: Louis
Email: louislewyc@gmail.com
His selling rate via sea shippng is
((total RMB include ship to 广东广州)*1.18)/1.8

I do not know how it will cost if by Air, since i always use sea shipping although it will take 3-5weeks to reach.

You could mention my name "edwardccg" if you concern when contact him. Or perhaps you could just buy from other someone who run this smiliar business from taobao.
Direct buying item from taobao and ship to malaysia also ok but i remember only EMS is available, not worth if only buy small stuff.
