I am collecting quotation recently, depending on how long & which type of 窗簾軌 (any bendings needed) & your house location & of course how high class of the 窗簾 shop.
I need 5 條窗簾軌 with bendings, installation fee vary from $450 - 800.
2條窗簾軌 300蚊 -> how long & any bending of the 軌, & which type? 手拉路軌?
