i called Matthew at Park Mall branch. He told me the black tempered glass is not scratch proof but is heat resistant, water vapour is ok.
I intend to take up the 3899 offer. So it consist of 3 Seater Sofa, 1 Grand Castle Mattress at King Size (To Top up 900), King size bedframe (To Top up 100), Black Tempered Glass Dining Set, 2 Latex Pillow, 1 Bolster, Leather Oil, Mattress Protector, TV Console (To top up 300). So it is around 5300. Is it worth it?
