Hi all, I saw the price of the wall paper as mentioned above which is about $100+ per roll. What is the length per roll? I dunno if I made a bad decision as I just purchased from De Page at IMM. They sold me a roll for $498 nett inclusive of installation. A roll according to them is 5 metres, height definitely can cover from ceiling from wall for normal HDB. Is that considered expensive? They told us they are suppliers. Can someone advise please?
