these are made near by Gypsum Mine, we use super white gypsum powders to make mode and cornice in good colour, some people like to brash new colour on the surface of cornice, so it is okay. and we support with any shape no matter it is chinese style or west Europe Style, we both know them. so you can try with us, shape's size can be very big, like 170 mm wide, it is okay to produce in our local factory, try to let us know your need!
